Unidentified manufacturer, unknown material, no tag, and unknown size, therefore it is being sold as a defective item or junk item. It's in a clean, unused condition, so I'm offering it to anyone interested. I received this as a sample, but it doesn't fit my body type, so I'm selling it. I was told it was size M84 when I received it, but if you're unsure, please refrain from purchasing. ◾️Size has not been measured. ◾️Unused and unworn. ◾️When shipping, due to thickness, the plastic collar supports and cardboard backing will be removed, and it will be shipped in simple packaging. ◾️There are no problems with the item itself, but please refrain from purchasing if you are particular about details or have any concerns. Please understand that this item has been stored by a private individual before purchasing. Thank you for looking!
