Did you lose or damage the container or tube that your moderator came with? They are usually made of cardboard and sometimes bite the dust when you step on them or they come apart with frequent use. One of my wife's medications come in this plastic container that is perfect to store most of my spare moderators. It measures 5 inches long and just a tad over 1 3/4 inches in diameter on the inside. If you talk the pharmacist at Walmart nicely, they might give you one or two. FWIW.
