Thank you for viewing my items! If you understand the product, you can buy it immediately ◎! This is a BITE ME comfort harness ☺︎ The size is M! I bought it for my dog at my parents' house, but the size didn't fit, so it's new and unused, only tried on once＾＾ The combination of yellow and light blue is very cute♡ ◎ If you have any questions, please comment! ◎ I inspect the items, but please consider that oversights and differences in opinions can occur. ◎ When shipping, I will fold it and ship it in the smallest size. ◎ Returns and refunds are not accepted after purchase. ◎ Please read the profile before purchasing. ◎ Please purchase only if you understand that it is a used item due to being stored by a private individual.
