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 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 because many customers who order requested no elastic. Please be sure to check your dog's size, considering the thickness of the pad you will use, before purchasing. It's a three-dimensional design 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. Please understand that the design may change as we consider whether there is any burden on the dog wearing the belly band and how to prevent urine leakage more effectively. m(__)m ★ If you are using the bulk purchase function, please let us know without setting a price.
