Asai Shoten Super Silicone Slurutto Cup, 4 pieces I used these for popovers, bread, and baked goods. They release very easily, making them easy to use. I used them with care, but I've decided to part with them due to decluttering. Please understand that this is a used item before purchasing. As this is a home-stored item, please refrain from purchasing if you are concerned about minor scuffs. They are relatively clean, but as they are used items, please do not purchase if you are sensitive. I will use recycled materials (reused cardboard, etc.) for packaging and shipping. For fragile items, I will use bubble wrap, rolled paper, newspaper, etc. as cushioning material. Please be aware that this will increase the amount of trash you have to dispose of, but it is for accident prevention. Please be sure to read my profile before purchasing. Thank you for looking.
