I made something similar with this device. you basically put the weed in and poke it down around this stick. Then you remove the stick and there's a hole inside.

It took me about 3h to smoke this tiny little cigar thing. it was dense. I wrapped it in weed leaves and coated with warm live resin to stick them down. waited 2 months to smoke it, left it sitting in a jar and burped it every so often. once the leaves were brown, I smoked it.

tasted great. but i'd never do it again, more of a fun project than anything. It sure was fun.

Agreed two weeks to master when they are just right they’re banging

I stick to my multi ingredients pure/blunt joints now

Cost skin in hash rosin - cover while hot with keif
Flip over do other side
Then pure weed, concentrates hash worms galore as the coated skin burns slow so allows time to burn shatter sugar wax hash even isolator hash with gorgeous bud
It’s defo a labour of love
