كشتبان مانع للانزلاق

The safety ridge on top really does keep the needle from sliding off, which was my biggest frustration before. It's snug enough that I forget I'm wearing it after a few stitches, a nice change from bulky metal thimbles.

Pricked my thumb one last time before switching to this thimble—the ridge keeps the needle exactly where I want it, no more slipping. Fits snugly enough that I don't even notice I'm wearing it after a few stitches.

The safety ridge on top really works—my needle hasn't slipped once since I started using it. It's thin enough that I can still feel what I'm doing, which surprised me.
