I purchased this in 2019 and have kept it in storage since then, but I'm selling it because I have no plans to use it. It is unused and unopened. ◼️Product Description◼️ Size: M Color: Red Brand: SHENMATE Closure Type: Buckle Care Instructions: Hand Wash Only Product Display Dimensions: 27 x 18 x 1.8 cm 【Soft Material】Made with soft-to-the-touch nylon material, it has a fluffy feel that won't rub against your dog's skin.
