I use a Brother PTouch label maker, which is good for labeling a lot of different things. I bought it years ago so I don't remember the exact model, but they make a number of different ones that use the same label tape. The label tape comes in different widths/colors, but I use the black-on-white 1/2" for most everything. My labeler takes up to 1/2" tape, but some models take up to 1". The laminated tape sticks well to most everything but doesn't leave much residue and what it does leave can easily be wiped off with a paper towel and a bit of alcohol.
