This is a Mercado bag I purchased from BASIC AND ACCENT several years ago. I've used it only in the summer for a few years. There's some slight shape distortion, and as shown in photo 3, there are about two spots where the corners are stretched, but I think it's within a range that doesn't affect use. Please refrain from purchasing if you are sensitive to these details. Material: Polyethylene Size: Approximately 29cm tall, 32cm wide, and 11cm deep at the base.
