Those mittens look amazing! The link says they are men's, so what size do you have? (I have very small hands.) Thank you for putting this together.
I think my granddaughter would love the tattoos and hair chalk. Thanks for the recs!
I've been pointing everyone to the "The Kid Should See This" gift guide - it's the best selection of STEAM gifts I've come across and I was able to find things for my kids as well as STEAM-loving grown-ups in my life! https://tksstgiftguide.tumblr.com/
(My kids are also loving the home TKSST site, which is a curated selection of STEAM-related videos for kids.)
