Thank you for viewing! This item is a ZAMST arm sleeve, size S. I've used it several times, but it's in relatively good condition with no holes or deterioration. It's breathable and has good absorbency, so it doesn't get stuffy even when you sweat, and it feels comfortable to wear. Unlike ordinary, inexpensive arm sleeves, it's tear-resistant and the material stretches well, making it easy to fit your arm. It suppresses unnecessary muscle vibrations that lead to fatigue, so you can really tell the difference between cutting with bare hands and cutting with an arm sleeve. I found it easier to cut when I was wearing it. Please refrain from purchasing if you are sensitive to items that have been stored at home. Thank you.
