I recently picked up some Boge cartos at a bargain price. When I took out the seal to fill one with juice, I noticed that there appeared to be a lot less filler material - by almost a quarter inch. Naturally they don't hold near as much juice as the Boges I was using before. I am fairly new to cartos so I don't know if this variation is normal, if Boge makes an econo version of it's cartos with less capacity or if the cartos I have are made by Boge at all. Packages are the same except for the label on top of the box. The larger capacity says "empty" and was sold as refillable. The other was not. Any ideas?
