To use this Plus-Plus Dragon tube set, simply open the tube and start building! Kids can create flat 2D designs on a surface or stack the pieces to make 3D objects. Encourage them to use their imagination and come up with unique creations. When you're done playing, keep the pieces in the tube to avoid losing them. Store the tube in a dry place away from direct sunlight. If the pieces get dirty, you can wash them with mild soap and water, then let them dry completely before playing again. Always supervise young children during play to prevent them from putting the small pieces in their mouths.
