life´s simple, go green

and just smile.

Join our adventure to change the world

by 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 where being sustainable is fun, affordable and easy.

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

We aim to reduce plastic waste by offering eco-friendly alternatives. Our first product line consists of sustainable bamboo toothbrushes wrapped in 100% biodegradable packaging: bamboo travel cases and craft boxes. We are now also offering bamboo cutlery sets and bamboo water bottles.

Moreover, we are engaged in giving back to society by collaborating with the international NGO Educate For. Every toothbrush purchased sponsors a pencil for children in South America.

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