Thank you for viewing my products. 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 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 requested it. ★ This fabric is out of stock, so this is the last one. Please be sure to check your dog's size, considering 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, considering whether it puts a 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 me know without setting a price.
