IL CANE | Breezy Stash Pouch
This pick up bag holder is light weight and easy to attach. Best of all, it won't break on you - unlike many of the cheaper, plastic pick up bag holders out there. Made from neopreen fabric and a matte faux leather, with a reverse coil zipper at the top, it has a clean, sleek look. Strictly designed to hold a roll of pick up bags, you could cheat, and throw a key inside for additional storage use.
Webbing loop at back secures the holder to your leash so it won't be dangling and getting in the way. Easy clasp at top attaches to d-rings at leash handle, or around the actual leash handle itself, if no d-ring is present on your leash.
