It’s just a normal, but thicker plastic bracelet. Yes, I’m talking about glue sticks and I needed to super glue the bracelet beforehand so I could work easier. I think it would be too weird, for me at least, if you went into one of those “diva” stores and bought one; that’s why, unless you have one lying around or something to that nature don’t worry about buying one. You can use other things, but that’s, like I said, the only home situation I could accomplish it with (and it worked better than I thought). Thing is with silicone you can’t hot glue (I guess you can, but you have to wait for it to cool down, but not down enough so it is hard) it so you’ll have to find some very strong super glue (like what I did to hold the bracelet in place before issuing the hot glue). $50 instead of $100+ is the way to go for pump+cylinder; if you can fit inside a 2”od/ 1.75”id gravel cylinder.
You could also just layer a bunch of hot glue on the end and outside, but it takes a steady hand to make sure the glue doesn’t layer up inside (that’s what I did with my other one); which doesn’t work as good as the method described in post #1.
