This is a set I have made for a Toy Poodle, featuring a leather collar with red accents and its matching rolled leather leash (1 m long), both made in hazel leather with solid brass fittings.
Here's the collar, with thin red leather accent running all around its border. 12 mm wide, solid brass roller buckle, additional removable loop:
While this is the thin rolled leash, 1 m long, with lightweight solid brass snap-hook:
Entirely handmade on measure and hand stitched, as usual.
