Thank you for looking. This is a set of plastic tableware for children. It's lightweight and microwave and dishwasher safe, making it easy to handle. It's reportedly made in Japan. It has been stored at home without being taken out of the transparent bag and never used. I would be grateful if someone who understands that this is a used item would find it useful. There are no smokers or pets in the house. The official page size specifications are as follows: Small bowl: φ125 x 65mm Cup: φ7.5 x 7.5cm
