Outer fabric: Soft quilting, gray Lining: Cotton fabric Interlining: ➖ 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-made 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 circumference (where the belt will be). (Around the navel) The length should be the waist circumference plus about 8-9 cm (including the diaper 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 and lining fabrics, I think it will prevent shape loss. ♪ 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. We recommend hand washing just in case. ♪ We will offer a discount for multiple purchases, so please be sure to comment before purchasing.
