Hello Kitty containers. Tupperware set Made in 1999 Made in Japan (Only the round container is marked on the back.) Size: Square: 550cc capacity Length: approx. 11cm, Width: approx. 15cm (including handles), Width: approx. 11cm (excluding handles), Height: approx. 6cm Round: 270ml Length: approx. 9cm, Width: approx. 11cm (including handles), Width: approx. 9cm (excluding handles), Height: approx. 6cm The lids are the type that simply cover the containers and are easily removed. There are no fasteners, and they are not designed to close tightly to prevent contents from spilling. They do not twist to lock. It seems they were made this way from the beginning. If you plan to use them as lunch boxes, please use a rubber band or similar. Please understand and accept that these are retro items, and there may be some overlooked details. When shipping, I will protect them from scratches and pack them together! I will use recycled packaging! I will ship at the lowest possible cost, so thank you.
