>>One of the bag sizes we use is approx 2.25” x 8”.<<<br><br>I’m trying to envision this.. tropical eels? :-) Maybe the next size up…<br><br>However, if the stored size of the bag were pretty much the same per volume capacity (pretty much impossible, I guess, given surface-to-volume ratio) multiple smaller containers would be preferable- get all your eggs out of one basket, so to speak.<br><br>>>They are gas permiable, which helps the fish by allowing the CO2 to escape and the oxygen to enter the water…. Buit what caught my attention was how elastic they were <<<br><br>Sounds like expanded PTFE, with a smaller pore size than Gore-Tex, thus avoiding all that licensing overhead.. but I’d expect that to be opaque. Were these transparent?<br><br>>>Unfortunately, they are not sold through retail. The few folks I know that use them ship enough to justify buying case lots from industry contacts they know.<<<br><br>BUT, at the probable cost in bulk, some enterprising outfitter might be able to mark these up 100 percent, maybe 200 percent, and they’d still be cheap for those just wanting a few- probably cheaper than (good) condoms…<br><br><br><br>
