Let me start by saying this unicorn-themed DIY water bottle kit is an absolute hit with kids! My niece (age 6) squealed with delight when she saw the sparkly stickers and colorful fidget keychain. The excitement of personalizing her own bottle kept her engaged for hours - a parenting win!

The pros are fantastic: The bottle itself is the perfect size for little hands (about 10oz), and we've had zero leaks thanks to the secure silicone seal. The included stickers are vibrant and surprisingly durable - after two weeks of school use and multiple washes, only 2-3 gems have fallen off. That fidget keychain? Genius. It's become her favorite stress-reliever during car rides.

Now for some real talk: The loose gems mentioned in other reviews? We tossed those immediately (choking hazard for younger kids). Also, the wand applicator is pretty useless - fingers work better. One minor annoyance: The lid's hinge pin occasionally loosens, requiring quick fixes.

Unexpected bonus: This bottle actually improved my niece's water intake! She's so proud of her creation that she constantly shows it off... while hydrating. We've used it at soccer practice, school, and even as a special "artist's cup" during craft time at home.

Would I recommend? Absolutely - especially as a birthday gift. Just supervise younger kids with the small parts and maybe add some extra strong glue for those determined gem artists!
