What can I say? It’s a nice rubber stopper. Even came in a supervillain purple color.

Very good plug for powder coating hydroflask bottles. I bought three other sizes trying to find the right size that will fit the bottles. This one fits it perfectly.

Perfect replacement for the stopper for my Frigorello glass refrigerator jug! Just a bit more lavender than the picture on my monitor.

Used these as TIG welding purge plugs.They work fine as long as the welding is about 1in or more away.They hold up to high temps very well.
