Tokyo Powder - BoostDESCRIPTION: BOOST is considered a primer layer to your chalk routine. It provides a sealer by adding a dry layer between the chalk and your hands. Each package of BOOST is considered multi use as only 1 2 small pebbles are needed per use. After pouring the pebbles into your hands, we recommend crushing them and rubbing your hands together. For best results, apply BOOST to clean hands, prior to adding other chalk.
