The pool noodle works for me, I think it will be good insulation on the water pipe!👍😀
I noticed a lot of people stamping stainless steel 304 or better quality 316 stainless steel washers with crypto seed words....
Looks like 3-D printers can print the stamping jig file for just pennies in plastic... since I don't have a 3-D printer I just ordered one it's being shipped for $12 plus 5 dollars shipping. You could probably make some money selling these!😀
