Purchased around autumn 2024 and used about 3 times in airsoft games. Selling to clear out inventory. Quoting from Amazon: Holds 6 M4 30-round magazines vertically. Can also be used as a dump pouch for shotgun shells or different types of magazines. When open, it's 8 inches wide x 8.5 inches long. I will offer a 500 yen discount if you purchase multiple items from my listings.
