It enabled all kinds of color combinations. *Both sides are made of premium Italian leather made of chocolate brown natural leather, two-layer construction Two pieces are stitched together and hand-sewn one by one with white yarn. While most leather goods are now sewn with machines, our brand finishes dog gear using traditional hand stitching. Although hand sewing takes many times longer, we boldly sew the neatly aligned seams with white polyester thread. (Hand-stitched doesn't fray, and even if a dog tears it, the leather will be torn, but the thread won't be torn and will remain connected.) ） *Size　 Size SS (red license holder) Width 1.6 cm Length 20~28 cm (hole position) Thickness: Main body approx. 3.5 mm, both sides approx. 3.5 mm (supple, not hard), firm type Weight: Light (designed to be sturdy and light enough to withstand load) Hardware: Gold (metal, large sizes are made of brass) *Features *Supple and firm.
