Outer fabric: Twill fabric, scallop pattern Lining: Cotton fabric Interlining: Thin quilt batting Length: 40 cm Belly side: 11 cm Back side: 9 cm Made in Japan, Velcro width: 5 cm Easy to put on and take off. Mainly for all seasons, breathable Uses Japanese cotton fabric. I think it's also strong for washing. ⭐ Depending on the fabric, it may shrink slightly when washed. The lining also uses high-quality Japanese cotton fabric. Measure your dog's waist (where the belt will be). (Around the navel) The length should be the waist measurement plus about 8-9 cm (including the sanitary pad) I think it will be the best size. Flat elastic is inserted in the part that touches the belly. Sizes may vary depending on how they are measured. If you are unsure about the size, please feel free to comment. (*^-^) If there is no size, we will make it depending on the fabric stock, so please feel free to comment. (*^-^) By putting quilt batting between the outer fabric and the lining, I think it will prevent the shape from collapsing. ♪ Can be used for diaper covers Overnight stays Going out Marking prevention Since it is handmade, please refrain from purchasing if you are looking for perfection. For washing, we recommend hand washing just in case. ♪ We will offer a discount for multiple purchases, so please be sure to comment before purchasing.
