Haifu II Sea Moon Booster 120ml - Upgraded version of the well-known Haifu booster, with a volume of 120ml. Apply the Haifu Sea Moon Booster only to the sponge of the rubber. Repeat the application every 24 hours for optimal speed increase. After the last layer, let the booster dry until the rubber returns to its flat form. Use water-based glue to attach the boosted rubber to your wooden blade. Ensure effective performance for 4 to 8 weeks. Note: The booster is not glue, so you will need ping pong glue to bond the boosted rubber to your blade. Warnings: The booster increases the thickness of the rubber. Make sure the total rubber thickness does not exceed 4.00 mm for matches regulated by the ITTF. Players are responsible for confirming the thickness of the rubber. Be careful when applying the booster to rubbers that already have speed effects from glue, as many modern rubbers already contain booster liquid.
