The "Block Lunch Box" is the thinnest lunch box on the market. The product is thin and measures only 3.5cm in thickness, with its length and width similar to that of a piece of A4 paper.

It fits easily into a briefcase, so that the briefcase directly replaces the lunch bag, making it more convenient for the user to carry; due to the unusual way to carry the lunchbox around, we have created the unique "separate seal" technology to separate and seal the different ingredients, ensuring that it is healthy and also maintaining its delicious taste.

The product has achieved a breakthrough of the traditional structural constraints and has hidden all structural forms through clever design, so that the product look like a square, and its six sides looks smooth and aesthetically pleasing no matter which side one is looking at.
