The Superior Labor – All Leather Engineer Key Case

The Superior Labor – All Leather Engineer Key Case

This key case is a miniature version of the engineer’s bag. Previously made from the same canvas as the engineer’s bag, it returns in a fully leather construction built to last even longer.

Crafted from domestically produced glove leather, it combines durability, flexibility, and lightweight comfort. Originally developed for baseball gloves, this leather is highly resistant to friction and becomes softer with use. The leather is core-dyed for rich, vibrant color throughout and finished with a special oil treatment that gives it a smooth, supple feel in the hand.
