Using the DX Zenkai Buckle is easy. First, insert the Sentai Gears into the buckle to start the fun. When you're done, you can store up to 6 gears inside it for safekeeping. As for the scheduled release in March 2021, keep an eye on your order status. If you've made an early bird or full - payment preorder, you'll get free shipping within the USA. When it comes to maintenance, just keep it in a dry place away from direct sunlight and rough handling to make it last longer.
