51 unique gifts to give your best friend - all under $100

The term "small but mighty" gets thrown around a lot, but this small Bose speaker is only a little larger than the phone used to control the music — and has a much bigger sound. It comes in three colors and has a six-hour battery life.

"Tinder Nightmares" is a modern horror story of Tinder exchanges organized by theme, with chapters such as Bad English, Broetry, Strange Requests, Sneak Attacks, and more. The Instagram account of the same name has nearly 2 million followers. But beware — like Tinder, this book is not for the faint of heart.

This subscription gift was handcrafted for bookworms. Book of the Month has been around since 1926, and it's credited with the discovery of titles like "Gone with the Wind" and "Catcher in the Rye." A team of experts and celebrity guest judges curate must-read books — usually new releases, hot topics, and debut authors — and send them to the subscriber's doorstep.

If they're more into audiobooks or e-reading, check out a gift subscription to Scribd (full review here).

Birchbox is a skincare and makeup subscription that sends tons of samples of new and cult-favorite products so subscribers can find products they love without committing to buying full-sized anything in the meantime. It's also a monthly excuse for them to treat themselves.

In a true gesture of friendship, deliver two pounds of only the best Starburst flavor to them.

Perfect for weekend trips or shoving into the overhead compartment of an airplane, Everlane's twill weekender is a pretty good deal for $98. It's 100% water-resistant, has leather straps, and includes little gunmetal feet for stability.

Everlane is also a good fit for friends who are concerned with transparency in business — especially with the company's new ReNew collection made from recycled plastic bottles.

Dagne Dover is one of our all-time favorite handbag companies, and most of that has to do with quality, style, and a peerless attention to detail. The Lola Pouch comes in seven colors of genuine pebbled leather. It has helpful features like elastic lip gloss loops, slip pockets with hidden magnetic closures for compacts and shadows, and a smooth lining that's easily cleaned. Zipper tabs can be unsnapped to adjust the shape, too.

This double wall, vacuum insulated stainless steel mug is especially perfect for commuters who would rather drink hot coffee than room-temperature for the 45 minutes on the subway — or any other time. We're big fans, and it does a pretty incredible job of keeping cold drinks cold for up to 24 hours and hot for up to six hours.

Especially good for long-distance best friends, this giant cardboard cutout of your face is one giant physical reminder that you care. Michael Scott once said that gifts were great because you can point to them and say "Hey man, I love you this many dollars worth." This gift also says "I love you this huge."

Book an experience like a pasta-making class, brewery tour, or local tour that the two of you can enjoy together. Plus, you can buy this gift as last-minute as you like.

Finding a convenient spot to place an open bottle of sticky, vibrant, and fast-drying liquid while you paint your nails is not easy. This $7 nail polish holder looks gimmicky, but it's actually pretty useful.

Adult coloring has had a resurgence in recent years as a great de-stressor (even Kate Middleton is a fan). It turns out, though, that adult coloring is even more fun with adult beverages. Here's one that combines both.

Artifact Uprising's brass and hardwood Display Box is a bit more aesthetically pleasing than the traditional picture frame. They can showcase their favorite picture by sliding it into the front of the box, and the box itself can hold up to 50 five-inch by five-inch Square Prints inside.

If you're just looking for prints, you can find those starting at $8 here.

A box stuffed full of chocolate needs no introduction, but this one is a pretty good deal. The box comes with 36 mini bars of gourmet artisan milk and dark chocolate, all made in small batches and free of artificial flavors. The 14 flavors range from sweet to savory, and each bar is only 60 calories.

This Celestial Silk pillowcase is one of the internet's hidden gems. It's $40 on Amazon, but we rated it the best silk pillowcase you can buy in our guide — and it gives you more silk per square inch than options twice the price at Sephora. It's made out of 100% Mulberry silk — one of the highest quality silks you can buy — and comes in 13 colors and three sizes: standard, queen, and king. It's the one I personally own, and it makes a big difference for frizzy hair.

Rupi Kaur's "Milk and Honey" is a New York Times best seller and a small cultural phenomenon. It's a collection of poetry and prose dealing with love, loss, femininity, and survival. If they already have this, you may want to look into Cleo Wade's new "Where to Begin" here.

Manduka consistently makes some of the best yoga gear on the market, and their cult-favorite Yogitoes mat towels aren't an exception — they'd probably be the main response if you asked around yoga studios for a mat towel recommendation. They have patented skid-less technology that uses 100% silicone nubs, and it makes a big difference.

Each Yogitoes towel is also made from at least eight recycled plastic water bottles, and the dyes used to make it are free of azo, lead, or heavy metal.

Maelove is a skincare company founded by a team of MIT grads (skincare obsessives, brain and cancer researchers, and chemical engineers) to make affordable, high-quality skincare accessible. The entire under-$30 line is supposedly great, but this $28 vitamin C serum (which people have likened to the multi-award-winning $166 C E Ferulic Serum) is the real showstopper — and it keeps selling out. I've tried it, and it does a great job of reducing hyperpigmentation, hydrating, and adding a "glow" to the skin. Read more here.

For the world traveler, adventure companion, or person who has a lot of places left to see before they're satisfied, this leather passport cover is one of the best mixes of quality for price you're bound to find. You can also personalize your gift further with a monogram (starting as an extra $10). Every time they use it, they'll think of you.

Whether they're moving, always talking about redecorating, or would love a gallery wall but don't want to expend the necessary brain power, they'll appreciate a Modsy gift. The service makes an exact 3D, digital replica of their room and fills it with actual pieces of furniture from well-known brands that they can buy on the spot.

This $75 cashmere sweater is one of the best I've worn, and it took me by surprise for $75. You can get it in either crew-neck or v-neck styles, unisex sizing, and ten colors. In person, the cashmere is one of the softest I've felt.

Plus, Naadam is a sustainable startup. They avoid toxic chemicals, invest in sustainable grazing practices, fund better vaccination programs for healthier goats, and use 100% clean energy to power production facilities. By cutting out middlemen, they pay nomadic herders about 50% more and charge about 50% less to customers without changing quality.

They're not a new name, but UGG slippers have stuck around for a very good reason: they're incredibly soft, durable, and made really well. The sole is sturdy enough to withstand walks to the mailbox, and the water-resistant material can take a little gross winter slush on the way there.

If you're looking for a cheaper alternative, check out Minnetonka — we're big fans of their mix of price and quality, too.

This now-legendary AHA and BHA at-home "facial" gently resurfaces the skin to remove built-up dead skin cells and reveal brighter, more even skin underneath.

This mini waffle maker may seem more gimmick than substance, but it didn't garner 1,000+ reviews just for being pretty cute. It's compact for small kitchens and people who only want to make three waffles rather than buffet quantities, and it's really easy to clean.

If they're more of a "one bottle per person" vino drinker, why not cut out the middleman with this twist-on bottle-to-glass helper?

A splatter guard gives you the benefit of an uncovered pan, minus the countertop cleaning and dodging of hot, popping oil.

Snowe's Diffuser has the advantage of looking more like home decor than a diffuser, but it also fills the room with a wonderful smell. Plus, the bottles of scent tend to last for months. Pick it up for a friend in five scent options that range from Speak Easy (leather, bitters, burnt cedar) to Pillow Talk (sandalwood, ginger, lavender).

Otherland is a candle company started by Ralph Lauren's former art buyer, Abigail Cook Stone.
