These are a brand new item from Essential Tactical. It is a nylon card backed with velcro that has elastic loops to hold 7 12 GA. shells. A loop of paracord is stitched to the top of the card to facilitate easy withdrawal from pouches or removal from loop velcro sections.
The "shotty card" was designed as a way to integrate shotgun shells to tactical gear such as M4 mag pouches and velcro ID panels. Additionally, a very cool mod can me made by applying a loop section of velcro to a side saddle for quick changes of shells from gear to shotgun. You can see it here
