James Y. ★★★★★ Oct 20, 2026

Picked up a set for a new dog collar project and the 0.5 inch version fits perfectly through the strap webbing. The finish is smooth, no sharp edges at all.

Miles G. ★★★★★ Oct 19, 2026

Finally got around to using these on a leather leash and the matte finish really holds the stitching in place without sliding around. The 0.5 inch size was a perfect snug fit for my strap.

Picked up the 0.38-inch rings for a dog leash project and they hold up nicely without any sharp edges. Finish is smooth and the cast metal feels solid enough for daily walks. Only wish they came in a slightly darker matte tone.
