Table tennis rubber HASS, red, 2.1mm thickness. - Brand: Sauer & Troger - Model name: HASS - Thickness: 2.1mm - Color: Red Length: Approximately 137mm Width: Approximately 132mm Used on the back of a Japanese penhold square racket, but used for less than 10 minutes. Personally, I felt it didn't suit a single-ply racket, so I am putting it up for sale. Purchase without comments is welcome! Thank you very much.
