This newest Vaporscope stem is designed to be easier to store and transport than the standard stem. The replacement of the fixed glass stem with a removable maple stem makes for a sturdier unit with less chance of accidental breakage. The glass stem by itself is 6 inches long and the wood stem is 8 inches long. Assembled, they measure just over 12 inches in length, 3 inches longer than the one piece, all glass Vaporscope stem. The hybrid stem also fits into our standard leather carry bag, which is a big plus for convenience.
