Ball & Chain eco-bag. This is an unused item I received as a gift. It has an "M" sticker on it, so I believe it's size M. Although it's unused, it has been stored at home, so the outer packaging has some damage (e.g., around the ribbon seal). The eco-bag itself is very clean. For those who understand the above. A paper bag will also be included. #ballandchain #macaron #ecobag #Msize
