I've been trying to find these http://www.flickr.com/photos/mrdat/2035954115/ online without any luck. They seem to be a sort of bag-in-box (mylar in the usa I think) for chemicals.

I'm having a hard time finding that specific model (already contacted the flickr member above (got no response) and contacted Delta1 (no response..) or any other type of bag-in-box, those things seem to be sold only in industrial quanities...

I want it to store XTOL and some other liquids.
Has anyone heard of it or knows where can I buy any sort of container like this (Mylar/bag-in-box)?
