Thank you for viewing my products. Length (side to side): Approximately 37cm Length (back): Approximately 8cm Length (belly): Approximately 10.5cm Belly circumference: Approximately 26-29cm ✤ 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 band because many customers who order requested it. Please be sure to check your dog's size, considering the thickness of the pad you will use, before purchasing. It is three-dimensional like a mask, so the important area is not pressed against the belly, reducing the feeling of tightness, and the navel area and the base of the legs fit snugly, making it less likely to leak urine. We may change the design, considering whether there is any burden on the dog wearing the belly band and whether we can 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.
