Outer Fabric: Oxford fabric with Nordic & star patterns Lining: Cotton fabric Interlining: Quilt batting (thin) 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, using breathable Japanese cotton fabric. I think it's also durable 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 wrapped). (Around the navel) The length should be your dog's waist plus about 8-9 cm (including a sanitary pad) This should be the best size. Flat elastic is inserted in the area that touches the belly. Sizes may vary depending on how you measure. If you are unsure about the size, please feel free to comment. (*^-^) If there is no size available, I will make it depending on the fabric stock, so please feel free to comment. (*^-^) By putting quilt batting between the outer and lining fabrics, I think it can prevent shape loss. ♪ Can be used as a diaper cover for: 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.
