The Stäck is the ultimate classic toy for your little one. Thanks to the unique design of each piece, it will become the ideal tool to introduce baby to shapes, colors, numbers and letters while having fun. Let them develop their hand-eye coordination, motor skills and spatial relationships by stacking, organizing, throwing and (of course) chewing them freely. Versatile and safe, feel free to bring them in the bath tub, sandpit or beach! Made of soft and flexible FDA-grade silicone, you can easily clean them, then nest them for storage or transportation. To try them is to adopt them!
