Painting edging tape

I hate applying masking tape when cutting in difficult edges. Even with the new blue tape, it takes too long, it is hard to get the tape into tough corners, the tape is too thick, and the edge is not straight.

Imagine instead a hard-edged plastic sheet, 6 inches long and 1.5 inches wide, with a sticky back. Just like the 3M tabs, but 6 or 12 inches long, on sheets. Easy to apply, and even easier to pull off with the tabs.
