New Balance Kids Neck Warmer / Muffler Navy Flat measurement: Approximately 21 x 24.5 cm I bought this, but my child didn't like it, so it's only been tried on. Please comment before purchasing to confirm availability. This is a personal inspection, so there may be oversights. However, I have priced it very low to reflect this. Please understand that I do not accept any complaints or returns. Regarding used and unused items stored at home, they are still "used goods" that have been handled by people. It is difficult to convey everything 100% to everyone through text and images alone, and there may be discrepancies due to differences in subjective views regarding the condition. Please consider the product description as a reference only, and refrain from purchasing if you are overly concerned about details.
