Each block features a different bright and enticing color that your baby will love. They have an embossed animal, shape or character on one side to help with recognition. The other sides have textured shapes for six sides of sensory development for your baby. The Squeak ‘N Stack Blocks are the perfect option if you want your baby to have blocks without the heavy and sharp traditional ones. They’re soft enough to be squeezed, making a squeak sound, but also firm enough to be stacked easily atop one another. These blocks are made of vinyl and simply wipe clean to keep all your baby’s favorite toys clean and sanitary. They also come with a vinyl zippered case. When playtime is over, just pack them up and put them away to keep your home neat and tidy.
