Black nylon wrist support, adjustable size for a comfortable fit. - Brand: FUTURO - Color: Black - Type: Wrist support - Material: Nylon - Size adjustment: Adjustable Soft cushioning material on the inside. Thank you for viewing. This type is used to fix the thumb. I bought it because I got tenosynovitis, but it hurt even with gloves, so I couldn't use the support. Therefore, I haven't used it much. There is a feeling of use, such as some fuzzing.
