Introducing Haifu II Sea Moon Booster, an enhanced iteration of the renowned Haifu booster. Volume 120ml. Apply Haifu Sea Moon Booster only to the sponge of the rubber. Repeat the application every 24 hours for optimal speed enhancement. After the final layer, allow the booster to dry until the rubber regains its flatness. Use water-based glue to glue the boosted rubber to your blade. Enjoy efficient performance for 4 to 8 weeks. Please note: Booster is not a glue, so you'll need table tennis glue to attach the boosted rubber to your blade. Risks: Booster increases rubber thickness. Ensure the total rubber thickness doesn't exceed 4.00 mm for ITTF-regulated competitions. Players are responsible for verifying rubber thickness; Exercise caution when applying booster to rubbers with existing speed glue effects, as many modern rubbers already contain booster liquid.
