3MScotchCode Wire Marker Tape Dispenser w/Tape STD-0-9, Includes 1 each of 0-9 numbered rolls

Q: How long are the tapes? I can't find the length anywhere so can't tell whether this will last me for 10 cables or 100. Thanks!

I can't tell precisely but I'd say more 100 than 10, probably 50 . I've done only one project so far with about 25 wires marked on each end. I've taken a photo of #5 roll so you can judge by yourself with thikess of the roll vs thickness of the tape: https://dl.dropboxusercontent.com/u/39875194/IMG_1281.JPG

Q: How small are the numbers? Can I wrap wires around rather than have tabs, so as not to tangle with each other? Thanks!

They are just over 1/4" tall. They could be wrapped around a wire but would prove difficult to read if the wire is not 10 AWG thickness or larger.

Q: plastic or paper numbers?

They’re like paper with almost like a laminated marker surface. They work pretty good in dirty environments.

Q: does this item come with the rolls of tape or do I need to order them? I want one that is already loaded with the numbers. Is this one?

It does not come with the rolls! I was disappointed in that myself. I would recommend finding a place that sells it already filled. It cost me more ordering everything separately.
