Description C2H4 (molecular formula for Ethylene) is all about the concept of chemistry. We are "CHEMISTS" because chemists mix different substances to create new matters, and that's exactly what we do. We take different elements from the universe, combine and reconstruct them to create new things. Every collection tells a story about the world or state and opinion about a topic. We are visionaries and scientists that creates furure.Satin NylonAdjustable cinch strap belt strap with press-release fasteningZipper closureCollection iconic logo embroidery and zippered compartment on frontZippered pocket on back PRODUCT ID 244533
