Using your Plus-Plus Yeti tube is super easy. First, just open the tube and pour out the pieces. Then, let your imagination run wild! You can create flat 2D pictures or build up 3D models. There are no right or wrong ways to play, so have fun and be as creative as you can. When you're done playing, put the pieces back into the tube to keep them organized. To keep your Plus-Plus pieces in good condition, avoid getting them wet. Also, don't expose them to very high temperatures. If they get dirty, you can gently wipe them with a dry cloth. Have a great time building with your Plus-Plus!
