Literally anything you want engraved on them.. your unit logo, your rank, billet, cutterman pins, coxswain.. a picture of your family, any image you find in google, mustache awards.. give me a challenge
Leather is Veg Tanned 4-5oz, 4” circles. Best for coffee mugs. Can do wet, does absorb.. but not as efficient as the cork.
Cork, 4” circle and square, thick and thin.
It’s honestly easier for my to do the 4 packs.. I already have to do the image editing into the engraver, let it run 4x and set a timer lets me work on another project.
