Kit Plip™ en silicone

My 6-year-old loves how the flexible arches bend without breaking, and the X connectors let him build surprisingly sturdy little towers. The pieces are just soft enough that he can snap them together himself, which keeps him busy for a solid half hour.

The ball-and-socket joints click together so satisfyingly, and the arches stay flexible enough that my kid can bend them into shapes without snapping. It’s been three weeks and these pieces still look brand new, which is more than I can say for our last building set.

My 5-year-old can’t get enough of these flexible silicone sticks and arches—the ball-and-socket connections hold tight enough for her to build tall structures, yet are easy for her small hands to pop apart. It's a huge step up from the rigid building toys she had before.
