Thank you for viewing! This is a novelty item commemorating the purchase of a Panasonic product: an EasyFlap 6-piece set of food storage containers that can be heated in the microwave with the lid on. Product Features: Microwave-safe with lid on: You don't need to remove the lid or use plastic wrap; you can heat and reheat food in the microwave with the lid on. Multi-purpose: It's very convenient as it's suitable for freezing and dishwasher use. Set Contents: A total of 6 pieces, including 3 containers of different sizes and 3 lids. *The exact sizes are unknown as the package is unopened, but the photos show that there are 3 sizes: small, medium, and large. Not for sale: This is a novelty item distributed as a commemorative gift for Panasonic purchases and is not sold to the general public. Product Condition: Brand new and unopened. I have stored it at home without using it after purchase. The packaging may have some minor scratches. [Please note] This product is a Panasonic novelty item, and the manufacturer may be a different company (such as "OCT" listed on the package). When using in the microwave, please ensure that the valve (air vent) on the lid functions correctly. Shipping: I will pack it with cushioning material (bubble wrap) and ship it via anonymous delivery. If you have any questions, please feel free to comment. Thank you.
