This is a set of Uniflame polycarbonate tableware I purchased about 30 years ago. It's now discontinued, and I can't find any images of it online, so I believe it's quite rare. The set includes four bowls and four slightly raised plates, all in a mesh bag. Material: Polycarbonate Heat resistance: 140 degrees Celsius Cold resistance: -30 degrees Celsius Made in Japan. Bowl capacity: 650ml Diameter: Approximately 16cm Height: Approximately 6cm Plates: Diameter: Approximately 20cm Height: Approximately 3cm Regarding the condition: It seems I mainly used two of the plates. One has a chipped edge, light stains, and minor scratches. The other also has light stains and minor scratches. The remaining two plates and the four bowls have no noticeable scratches and are in relatively good condition. A mesh bag is included. Uses/Purpose: Camping/Picnics Material: Melamine/Plastic
