The DONIC BLUESTAR A1 is a high-performance table tennis rubber featuring Optimised Energy Sponge (OPTE) technology, which enhances elasticity, dampening, and overall playability. With a fine-pored 52.5° sponge, it delivers a strong catapult effect, combining high speed with excellent spin. The slightly sticky yet extremely grippy top sheet allows for precise, aggressive strokes, making it a powerful choice for offensive players. Praised by former world champion Jörgen Persson, this rubber adapts well to professional-level play while also benefiting ambitious players who train intensively. Whether attacking close to the table or from mid-distance, the BLUESTAR A1 ensures explosive performance with reliable control, making it ideal for players seeking speed, spin, and precision in their game.
