Handmade dog cart cushion. Reversible design. The filling is 100% polyester, so it can be washed. Hand washing is recommended to prevent the cushion from losing its shape. Please reshape the cushion before drying. Would you like to create an original cart cushion with your favorite fabric? Please let me know your desired finished size. If you don't mind, please tell me your dog's breed, name, and gender. Custom orders are welcome. The finished size may vary slightly depending on the amount of filling. Please understand. If you would like a fabric other than the samples, I will post the fabric options, so please let me know. If you would like non-slip fabric, please let me know. An additional fee of 600 yen will be charged for non-slip fabric. Please understand. Please note that this is a handmade item, so there may be some stitching irregularities and distortions. Please purchase with understanding.
