Heat resistance: 130 degrees Celsius Manufacturer: Osaka Angel Purchased for my grandmother, but never used, so it's new. I thought my child could use it, so I used it for naptime at nursery school for a week, but I prefer ones with elastic bands, so it's been stored at home. There is a name written on it. I've blacked it out in the image. When I re-cleaned it for sale, I noticed a faint 3mm spot and a dot stain (see photo 9). I am a self-proclaimed inspector, so I may have missed something, but it was only used for a week, and the condition is good, so I think it can still be used. Thank you for looking.
