This sorta came outa nowhere- found on the Big Bad Toy Store Website:
Load up big-time for any VORTEX mission with the Ammo Belt Kit! When you strap on this Ammo Belt with its 10-disc magazine, you can stay heavily armed even while you’re on the move. Load the magazine with 10 of the 15 included VORTEX discs and attach it to your Ammo Belt, and you’ll still have room for a second magazine (sold separately)! With all the ammo and firepower you can fit in your Ammo Belt and your blaster in your hand (sold separately), you’ll be ready for any battle situation!
• Ammo Belt Kit lets you carry along lots of extra firepower!
• Belt features clips for 2 magazines!
• Includes 1 magazine and 15 discs!
• Magazine holds 10 discs!
• Load your magazine, then store up to 25 extra discs in the ammo pouch.
Cheers to Mr K from Adult Fans of Nerf for the heads up.
