Outer fabric: Twill fabric with an American pop can badge pattern Lining: Cotton fabric Interlining: Quilt batting (thin) Length: 44 cm Belly side: 13 cm Back side: 10 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 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) This should be the best size. Flat elastic is inserted in the area 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 available, we can 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 for diaper covers, Overnight stays, Outings, 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.
