Thank you for viewing my products from among many others. Length (side to side): Approximately 41cm Length (back): Approximately 8cm Length (belly): Approximately 11cm Belly circumference: Approximately 30-33cm ✤ The size of the belly band is the measurement from end to end of the tape. You can adjust it, so there is a margin of 1-2cm. (Depending on the thickness of the pad) The surface is oxford fabric. The belly side uses knit material. A thin interlining is attached to the center of the belly side. ★ This fabric is out of stock, so this is the last one. Please be sure to check your dog's size, taking into consideration the thickness of the pad you will be using, before purchasing. It's designed to be three-dimensional like a mask, so the important area isn't pressed against the belly, reducing the feeling of tightness. The navel area and the base of the legs fit snugly, making it less likely to leak urine. Please understand that the design may change as I consider whether there is any burden on the dog wearing the belly band and how to prevent urine leakage. m(__)m ★ If you are using the bulk purchase function, please let me know without setting a price. This is made as a hobby, so there may be some imperfections such as loose threads, distortions, and slight size errors. If you cannot understand this, please refrain from purchasing. m(__)m
