♦ Instant purchase OK ♦ Ships within 24 hours ♦ Anonymous delivery ♡ Set of 2 experiment kits! New ♥ Mysterious experiment kit! Water that changes color & a mountain of glowing crystals I bought these when I went out of town because they weren't sold nearby, but I ended up not using them. ⭐⡱ It's fun to do experiments with your kids, right? You can do them at home, so it doesn't matter if it's winter, and it might even be a good topic for a diary! If you want to enjoy experiments at home, please do! Thank you to anyone who will use them (*ᴗ͈ˬᴗ͈)ꕤ*.゜
