Thank you for viewing. I purchased a set of 25 and only used 2. I'm offering 20 pieces + a bonus. I used them from the top and haven't opened the bottom, so please consider them as spares in case of any defects. If you wish, I can also include the receipt from when I purchased them. I used these to hold ohagi (sweet rice balls). Although they are new, they have been handled by someone else, so please refrain from purchasing if you are sensitive to this.
