i think the type he is refering to are the round ones similar to a pill bottle. try Brownell's, MidwayUSA, MidSouth Shooters Supply or CTD. they may have what you are looking for. look for the type that hold just one choke tube.
another suggestion, check with your local pharmacy and see if they could supply you with a pill container. they come in many different sizes and should be one that will fit the loop on the holder.
