X-Raypad Obsidian PRO Air U-PE Universal Dot Mouse Skates – Less Noise

Great resistance to wear. Regular Obsidians were ground down within a few days of use on glass but these have kept up for at least a few days and show only minor use compared to very obvious flattening in regular Obsidian after same amount of use. Take note that they are a larger diameter and also slightly higher than most dots. The height will wear down from use (although it is resistant).

Great product. Customer is good as well. Highly recommended for glass.
