ONA TSA Lock

The TSA keyhole means security can open it without cutting anything, which was my main worry after losing a cheap lock to bolt cutters last year. The metal body feels solid in hand and the shackle snaps shut tight.

Bought this for a checked bag after a zipper pull got mangled on a previous trip. The metal body feels solid and the relock-without-damage thing means I'm not worried about security cutting it off. It's small enough that it doesn't dangle and snag on the carousel.

Bought this for a checked bag and it survived two international trips without a scratch. The TSA feature is the real selling point, security opened and relocked it in about a minute without breaking anything.
