Tupperware Crystal Wave Set of 3 Tupperware microwave-safe containers (with instruction manual) Although new and unused, these have been stored at home stacked together, so there are some minor scratches on the bottom. Therefore, I'm listing them as "Like New." Please refrain from purchasing if you are concerned about this. One container can be used for preparation, heating, cooking, and storage. Large (Blue Seal) 1L Approximately 18.5cm diameter, 6.5cm height Small (Yellow and Red Seals) 800ml Approximately 15.5cm diameter, 8.5cm height 600ml Approximately 15.5cm diameter, 6.5cm height Instant purchase is welcome!
