True Tape Supertape 3/4" X 3 Yard Roll Non Glare Lace Wig

I have alopecia, no hair, wear lace wigs and a nylong wig cap. Will the tape still hold the wig in place with the nylon cap underneathe?

Is this tape good for waterproof or swimming? Full submerged swimming that is.

Does the tape work with the c-thru base. And how long does it last.

Is there only one item roll
