These are Pacemaker UK's fair trade bags made by a "co-operative of 300 Filipino women." They are made of "non-biodegradable juice and sauce packs" - quoting from the tag.

I have the colorful shoulder bag in the middle on the far right, next to the red and white bag. I love it, it's very unique and pretty sturdy. Plus it's an awesome way to recycle waste.

My mom picked this up for me as a gift from a fair trade store in Liverpool, but unfortunately I don't know the name; still, I'm sure I've seen people with these in Canada. The price was actually 20quid, which is a little over $40CAD
