Using this Playfoam Naturals is easy! First, take out the packs of Playfoam and the cards. Pick a card with a letter or number on it. Then, start squishing and shaping the Playfoam to match the shape on the card. This helps with sensory and motor skills and learning letter and number formation. Keep the Playfoam away from small children who might put it in their mouths. After use, store the Playfoam in its original packaging to keep it fresh. Don't expose it to extreme heat or cold as it might affect its texture.
