The Launcher Grip is an Accessory released as part of the Beyblade Burst series. It was released in Japan on July 18th, 2015 and on April 2nd, 2016 for 600円. It was also released on March 17th, 2018 for 648円.
Due to the cover that is required atop Beyblade Burst stadiums, many Bladers find it uncomfortable or even impossible to launch within the small diameter left, especially when playing against an opponent.
Additionally, most Launcher Grips are manufactured too tight and it becomes extremely difficult to remove certain launchers and grip accessories from them. A considerable amount of force has to be exerted to slide them off of the Launcher Grip.
