I am selling this item to organize my table tennis equipment. Butterfly - Model Name: Dignics 80 - Color: Red - Thickness: 2.1mm Tokuatsu (Extra Thick) This rubber was used for about 4 hours for testing. The size was used on a Timo Boll ALC blade. The free chuck has been cleanly removed. Please judge the condition from the photos. I will sell this to someone who understands that it is a used item. Thank you.
