Regular backpacks just don't work here, and leaving a helmet on the bike is kind of scary. I bought myself a motorcycle helmet backpack with a large special compartment. I liked that it has a USB port, so you can charge your phone on the go. The material is waterproof, so nothing gets wet in the rain. And in general, it's comfortable to carry, the straps are wide, your back doesn't get tired.

norm!

I'm thinking about getting a portable thermal tattoo printer, but I don't want to end up with a model that doesn't do a good job of transferring fine details. I've seen a few options, but the reviews are mixed. Who actually uses one? How well does it transfer complex designs onto thermal paper?
