Elastic Pistol Mag Pouch

I really like the Unobtanium Gear “5X/3X HANDGUN MAGAZINE POUCH V2” and I want to get a single version. They said they can’t make it and I can’t find anything comparable.

Any recommendations? I like how simple and minimalistic it is, it’ll be going on the sides of my Spiritus Mk5 placard to hold a multitool and flashlight.
