I want to start keeping xtol and ECN-2 chemistry in wine bladders within a box rather than reused 1L plastic bottles. However, I am having a hard time finding refillable three liter and five liter astra pouches that come with the carton. I have found combos that have the single use bags and the cartons. I'd like the carton for ease of storage in my closet and ease of dispensing.

Does anyone have a source to buy refillable bladders with cartons? Perhaps there is another brand out there that isn't astrapouch.

As the title states, looking for a m42 mount 35mm f2 lens for my spotmatic spII. Specifically version 2 which has a 49mm filter thread.
