The Magic-Flight Draw Whip is made of silicone and finished with acrylic tips. It comes in the 1-foot Whip which is huge for personal use and has the best ever draw time. The Draw Whip cools the temperature of the vapor, allowing you to inhale more vapors at a time. Now show me a metallic meal box that you could put in your dishwasher. Another great thing is a lot of these come with huge laptop lunch ideas and recipes that fit completely in the bento lunch box.
