Very nice and THICK plastic clips. Heavy-duty plastic!
So I actually intended to buy a 14mm plastic Keck clip to use with my quartz cap mega (the plastic clips seem to hold everything together better than the metal clips) but I accidentally ordered the 19mm plastic Keck clip. Now, I also have an 18mm quartz cap but I am working with a 14mm connection on my bong, so I always need an 18mm to 14mm reducer to use with my 18mm quartz cap anyway - and the 19mm plastic Keck clip holds the reducer to the 18mm quartz cap stem perfectly! I definitely like plastic Keck clips better than the metal ones. These clips are very heavy-duty plastic. Not flimsy or cheap-looking at all. Also, no worries about using a big torch right above these plastic Keck clips --- they don't even get warm when I am heating my 18mm quartz cap with my Blazer Big Buddy torch. Awesome and definitely worth the money!
