To use the Plus-Plus Alien tube, simply take the pieces out and start sticking them together. You can create flat 2D designs on a surface or build up 3D structures. Let your imagination run wild and make all sorts of alien - related shapes or anything else you can think of. When you're done playing, put the pieces back in the tube to keep them organized. Keep the tube in a dry place to prevent the pieces from getting damaged. Avoid exposing the pieces to sharp objects as they might break. If the pieces get dirty, you can gently wash them with mild soap and water, then dry them thoroughly before storing them again.
