These straps are a full grain oiled/waxy leather with a very light pull up. The strap pictured was stitched in a Plum thread. Horween Heavy Double Horse Fronts (DHF) are quite a rarity, in fact only a limited quantity of these hides are produced every month.
The 4.5mm thick strap is supplied with a 304L “Screw-in” stainless steel buckle in your choice of finish. (If you're planning on keeping your original buckle, please select the “no buckle required option” from the drop down, this will help a very small business continue to grow).
