I never really worried about it too much to ask, mostly cuz he's been doing it since '94, but also cuz they're cheap enough to "take a chance" on a couple maybe...? Remember, too, it's gonna vary quite a bit along the piece the more it's "worked"... but I'll try to get us answers as to what the starting thickness(es) of the tubing used is sometime today...

Me:
"People are showing interest in your Handels and asking for specific details about your products... I'm happy to relay them to you/for you if you don't feel like looking into membership as a vendor and fielding them yourself....?
For instance people are interested in the exact type of tubing you're using... whether it's boro, annealed, German etc as well as the size and wall thickness of the blanks used
Shit like that"
Craig @ SimpleGlassTubes:
"Yes German schott glass the handles are made 26x4 mm boro always annealed

Me:
"Sweet!"
