Sorry for the late reply yes they ship to uk
They come in 15g packs. I took the full pack. Got strong visuals which lasted hours (don’t ask how long-I lost track)
Didn’t experience ego-death or anything spiritual mind.
I’ve ordered 3 more of a stronger variety :)

Joints are great. I’m bad at rolling so used cones for a bit. Pretty good. I’ve always opted for a pipe with a sealed chamber when i have wanted to smoke stealthily though.

i’ve found the Budbomb to be the best. You can just fill the chamber and take it out to the pub or wherever and take a quick hit- there might be better options these days- i’ve not checked for a while.

Joints are really enjoyable but they burn at a constant rate and the smell is more likely to linger and be detected, whereas a pipe provided you with a few nice hits, and save for exhalation, it doesn’t cause any further smell.

They do build up resin which smells, but so long as you clean it regularly it works perfectly and your pipe will not be detectable by smell.

I just have an old protein mixer cup full of isopropyl alcohol and coarse salt (costs about a fiver) and drop the pipe in for a few minutes and then rinse it off. The alcohol lasts a long time before you need to change it out.

Dead easy! pipes in my experience are also more efficient as you’re not burning off anywhere near as much weed between tokes

best of luck!
