Thank you for viewing my products from among many others. Length (side to side): Approximately 45cm Length (back): Approximately 9cm Length (belly): Approximately 12cm Belly circumference: Approximately 34-37cm ✤ The size of the belly band is the measurement from end to end of the tape. You can adjust it, so there is a leeway of 1-2cm. (Depending on the thickness of the pad) The surface is made of oxford fabric. The belly side uses knit material. A thin interlining is attached to the center of the belly side. ✤ We have changed to no elastic as many customers who order have requested it. 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 is not 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. The design may change as we consider whether there is a burden on the dog wearing the belly band and how to prevent urine leakage more effectively. Thank you for your understanding. m(__)m ★ If you are using the bulk purchase function, please let us know without setting a price.
