My first constructions - PLAYBIO. Babies and toddlers can play with stackable jumbo buttons with rounded edges that are made of a durable and completely safe material. They are soft and easy to hold and can be inserted in the perforated flower-shaped board or stacked to create higher and higher towers safely. A total of 13 pieces. Ideal for ages 1 to 4. Measurements: 30 x 29 x 7. Organic product: yes.
