Thank you for viewing! I'm introducing Kaleido Gears, purchased from BorneLund. This set of blocks and gears features colorful designs typical of Italy. The variety of gears and connecting parts stimulates creativity. When the gears mesh together properly, just moving one gear will cause all the gears to move in unison! Children are thrilled by this discovery and surprise. The patterns on the gears reveal different charms as they rotate. It's so interesting that even adults get absorbed in it. If your child is young, you can assemble it for them! They can enjoy it just by turning it and experiencing the visuals and sounds. As they get used to it, your child can assemble it themselves. They'll learn to think about how to build it, as slight differences in distance can affect how the gears turn. - Brand: Quercetti - Product Name: Kaleido Gears - Number of Pieces: 54 pcs (One white piece that inserts into the gears is missing compared to when it was sold) - Target Age: 3-7 years old - Colors: Multicolor (Red, Blue, Green, Yellow, Purple) 【Request】 This item has been used by a child, so please check the details in the product images. ※ One of the four legs of the gear-turning piece is damaged, but there are no problems with insertion or rotation. ▼About Quercetti Since its founding in 1950, the company has developed toys that attract children's interest, nurture their creativity, and aid their growth.
