Swappable PopGrips allow customers to swap out their PopTops, to allow for wireless charging, and have all the same perks as the Original PopGrips. To be able to swap out a PopTop, customers need to have a NEW complete Swappable PopGrip to start. Once customers have a complete Swappable PopGrip, they can choose to buy a Swappable PopTop and swap out as much as they like!
