Those are high temperature o-rings. I ordered the 14, 15 and 16mm (OD, outer diameter) o-rings. The 16mm ones fit the best.
Lots of salty folks in this thread about the price.
This is a premium product, premium made. I don't think it tries to be the "best value", just "best".
Anyway, new price is less expensive than a Staroma XL kit and that one is made in Malaysia.
I vape less than 10g/6 months and I still consider myself as someone who vapes cannabis. I just do one or two bowls a week. Cannabis is laughably cheap when 0.2g sends you to the moon.
O-Rings would be a perfect solution (because you could use the same glass) but there aren't many options that can stand ~600F.
Making the diameter smaller would mean less capacity (therefore less "XL") but that could be an option given to the customer and be an extra stem or something.
I think...
Well, I joined the club. Girlfriend got me an XL after stalking my reddit account to see which plug in vaporizer I was most interested in. It's really great. Just wondering where to get extra domed screens (in Canada) for the "adjustable bowl" stems. Maybe I can use regular screens and shape...
