[Used] Neck Corset Supporter Cervical Spine Mesh Cushion (L) FREE BIRD Neck Corset Supporter Cervical Spine Breathable Lightweight Washable Mesh Cushion (L) https://www.amazon.co.jp/dp/B0F79D5CZ3?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 It didn't quite fit, so I'm selling it. Used for about a week. It's in good condition with no wear and tear, but there's one spot where the fabric has become slightly fuzzy. L size, Velcro closure. The part that touches the neck has a cover, and this part can be easily removed and washed frequently. The inside of the main body is like a sponge, so if you can dry it in the sun on a nice day, you can wash the whole thing. Shipping is planned via regular mail (teikeigai).
