Not only that, teflon tape is super cheap compared to electrical. If you have a couple dollars, you might be able to buy yourself a couple of rolls of teflon tape.
Another thing, too... electrical tape is porous. I wouldn't want to have that on newly stretched ears. Your skin has a chance of literally healing into the tape, which is scary. lol Granted, it doesn't happen to everyone, but we can't predict who it does happen to. Don't take the risk, you know? I'm glad you took the tape off!
And try to buy yourself some steel/titanium/glass plugs if you can afford it here soon to replace those tapers.
