It’s a play on words, because the bags that Flat Bags make are all made from recycled bike inner tubes and rediscovered fabrics. As they state on their Website:
“We are happily responsible for reusing over 15,000 ft of inner tubes!”
This company has been around since 1996, and now a main part of the business is to collect bike inner tubes and seeking out some really nice fabrics, which are fun and colorful.
Prices are around $90 and rise to around $130, depending on style size etc.
