Excellent size for wire labeling

Works great, legible, robust but not too thick. Excellent for labeling tefzel-insulated wiring.

This size works well with 18ga MTW
Avid Amazon Buyer✓ Verified PurchaseJuly 25, 2023
I recently labeled about 350 wires with permasleeves. This saved me from peeling the backing off that many labels and rolling them on the wire. It's not a huge time saver - unless you are producing labeled wires on a workbench with the proper gadgets to support speed. The main benefit, after not having to peel them, is how uniform and special they look. I was mostly doing 18ga MTW with a pretty thick insulation, and the fit was good. At times I had someone printing them out for me, but it would have been nice if they could open them as easily as I could, would have saved more time. This is the good news. The bad news: they can be tough to open to fit on the wire, if wire is pre-stripped the strands want to catch on the sleeve so you may need to wind them first, cannot use quick strippers if the label is already on and close to the end, the printed characters may shrink or become distorted after shrunk, when using open flame it can brown the label or burn the wire insulation, they are not as stuck in place as sticky labels so they may slip, and last but not least...they are expensive.
