Thank you for viewing my products from among many others. Length (side to side): Approximately 49cm Length (back): Approximately 10cm Length (belly): Approximately 13cm Belly circumference: Approximately 38-41cm ✤ 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 thin cotton material (sheeting). The belly side uses knit material. A thin adhesive 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 made 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. The design may change, considering whether there is a burden on the dog wearing the belly band and whether urine leakage can be prevented more, so please understand. m(__)m ★ If you are using the bulk purchase function, please let us know without setting a price.
