| | Re: Bottlecap lining on premade caps? Help.
You can stick a magnet to the liner with E6000, but it won't stick as well ( if you try hard enough, you can peel the magnet off - but who is going to try to peel the magnet out of the bottlecap? )
But, if you prefer taking it out, use very pointy tweezers to get under the edge of the liner and peel it up that way. It's a pain, but it works and leaves the cap clean.
I know from experience, my first bunch of bottle caps had liners!
