Spring-based zipper locks?
 

Around 18 years ago I bought a set of 3 small combination locks from the Sharper Image. I liked them in particular because they:

1. Had a spring mechanism, so even if the dials were set to the correct combination the locks would stay closed until I squeezed them open, and

2. Had dials that couldn't be dialed backward past zero, so I could open the locks without looking at them.

Does anything like that still exist? Last month I misplaced my last one. Last year I bought a few Eagle Creek locks, and I've already lost two because I'm not used to actively closing them and turning the dials to keep them closed.
