We wanted to find ways to become more sustainable

...but we couldn't find any.
 That's why we started Just Smile.
To create and provide easy & fun solutions

to adopt a greener lifestyle. 

Join our adventure to change the world

starting with a sustainable toothbrush and a smile.


/ Our Vision

Just Smile is a Belgian start-up which was founded in Tokyo, Japan.

Our vision is to create a world were being sustainable is fun, affordable and easy.

Instead of boring, expensive and difficult. 

Our idea is to encourage people to adopt a more sustainable lifestyle.

For this reason, we created stylish, colourful and creative products.

Together, we can make our earth cleaner and greener! Let's start today! 

/ Our Mission

At Just Smile, we aim to reduce plastic consumption by offering eco-friendly products as an alternative to plastic items.

As a first product, Just Smile offers sustainable bamboo toothbrushes wrapped in 100% biodegradable packagings: bamboo travel cases and kraft boxes.

  Moreover, we are engaged in giving back to society by collaborating with an

International NGO Educate For  which is leading different projects in Japan, Peru and Chile.

Every toothbrush purchased, sponsors a pencil for children in South America.

Thus, when you purchase Just Smile products you contribute to the reduction of plastic consumption and to the fight against educational inequalities.
