This tape belongs in the crafting toolset of every creative fairy. Stick it to the back of a metal frame and fill it with resin and other magical things. The tape prevents any leaking until you have cured your work. If you remove the tape afterwards, no glue residue will spoil your joy. Magical! You get 5 meters of transparent temperature-resistant tape in 4cm width. For a piece of jewelry usually a few centimeters are enough.
