I've lowered the price a bit! Size 5. Width: approximately 4.5 cm. Thickness: approximately 4.5 mm. The item is very good quality and quite stiff, but the color has faded slightly from use! Because it's stiff, the obi (sash) can easily slip out, so I'm also including an obidome (sash clip). The second and third photos are of a model. My name and the Kyokushin Kaikan logo are embroidered on it without any backing. When you purchase it, I will remove the embroidery of my name! I do not accept returns. Thank you very much for your consideration.
