Project overview

Mercari aims to create a society where items that no longer have value to someone are accessible to someone else who needs them. However, we face an increasing amount of packaging materials going to waste due to the rapid growth of the e-commerce market.

With the aim of offering a reusable choice for packaging materials, Mercari launched the Mercari Eco Pack in June 2019 and distributed about 10,000 units on a trial basis. Through this experiment, we were able to test whether users would accept reusing packaging materials as a new practice and culture.
