Do you use a foam stopper with this flask? I've got one on it's way but I'm having trouble finding a source for individual foam stoppers. The required #13 stopper measures 68mm top - 58mm bottom. This appears to match up to an Identi-plug L800-G (66-75mm) but I have only found a case of 40 available on the net for ~$55. The L800-E (46-65mm) might fit as well, but the same situation exists.
Any sources out there?
