I just had someone order a set and advise me that these are in short supply these days…
I don’t stock them but can get them quite easily… $225 shipped anywhere in Canada.
I wont give an explanation of quality or whatever, they’re from China… that’s all 
This is an older pic from a couple years ago but the set i delivered today was identical.
I have had my own version under development for sometime with samples ready i just havent got around to testing them… if there i find some demand i may hit it a little harder.
