I LOVE this packing tape. I use packing tape all the time in my Resin Jewellery projects with the backless bezels. You just tear off a piece of the tape and attach it with the sticky side facing upwards to a business card or something similar, with another piece of tape. Then, you press the backless bezel onto the tape and really press down firmly so there are no gaps between the bezel and the tape. Then you mix your resin and hardener together and pour it into the bezel. The reason why I love this tape is because it sticks so well to the bezel and it doesn't leave too much of a residue behind when you pull it off the bezel and hardened resin. Plus, any residue that is left behind can be easily removed with some acetone. But the main benefit for me is how well the tape sticks to the outside of the bezels, especially as I usually make about 10 of these resin filled bezels at a time. I thoroughly recommend this tape for its staying power! Thank you Craft Riot for a great product at a great price 👍.
