This is a foldable eco-bag that can hold four 500mL bottles! It's compact enough to fit in a dress shirt pocket, but surprisingly spacious. - Brand: Danke - Model Name: Register Bag S - Capacity: 500 mL × 4 - Foldable: Yes - Pocket Size: Same size as a business card holder I'm selling this because I have too many eco-bags and am decluttering. If you're looking for a compact eco-bag, please consider it! Thank you! ♡ #compactecobag #mensecobag #monotone #danke
