I have to mail packages frequently, so I use a lot of tape. Scotch brand is heavy-duty, does not "shred" like some tapes, and works in all temperatures! It also fits in a handy red "holder" with tearing "teeth" on the end, so you can roll the tape out, cut it on the teeth, and use it quickly. It you're trying to hold a very full box together, you need that tape in a hurry! I buy these refills, which usually come in a pack of two, and I've found ths particular tape works better than any other tape I've used. Since it's clear, you can also put a piece over your mailing label to make it waterproof just like the seams of your box! I couldn't do without it.
