My daughter got this as a gift for her 5th birthday. Best I can tell it's basically approx 100 pony beads and about 20 actual color changing beads. You use droppers filled with warm and cold water to color change.
She does enjoy it, but bc there are so few color changers she's been using just the pony beads to make necklaces and bracelets. Those beads are only [$] for a bag of 500 at most craft stores. I'd suggest saving your money and for less than half the price buying some of those and other fancy beads at your craft store.
Used the kit with Girl Scouts ages 11-13. They love making friendship bracelets - the supplies were great, with nice variety - but many of the patterns were complicated for them. They want to crank out bracelets more than take time to make interesting weavings.
We bought this kit for our 7 year old for her birthday. She was so excited to open it and we immediately threaded the needle with the thread so she could get started. The problem is that the needle provided does not fit through at least half of the beads in the kit! We tried to use a smaller needle from my sewing supplies, but then we could not thread the thick thread that comes with the kit through the hole. We will be returning this kit to Target this afternoon. What a big disappointment.
