Thank you for viewing. This is an accessory for a 3on3 Bey case purchased on Mercari. It can be combined with the official 3on3 Bey case to secure the Beyblades. Please check the photos for the appearance and how to set it up. I purchased it three months ago and used it when carrying it around. I was told by the previous seller that they made it themselves with a 3D printer. My child is retiring from Beyblade, so I am selling it to organize their collection. Only the contents are included; the 3on3 Bey case is not included. Beyblade X Bey case 3on3 3on3 Bey case Case Accessory
