WHAT WE DO

Leather goods from Lies Mertens combine efficiency and elegance in a sustainable way.

We focus on high-quality materials, details and functionality.

“How can we create something with as little elements as possible?” It’s a question we constantly ask ourselves, aiming to create timeless designs by reducing superfluous components. To guarantee supreme quality, we only design a limited number of bags every year, which we perfect in aesthetics and ease of use.


WHY WE DO IT

Brands should try to make a positive impact on the world. That’s why we exclusively work with bio calf leather, which consists of all-natural products that don’t harm the environment.

We also highly value a safe work environment and fair wages for all our partners. Our bags therefore are designed in Antwerp and handmade in Portugal, produced under sustainable conditions.

We want to create functional and straightforward designs, suitable for everyday life. Below, you can find more information about our brand and values.


HOW ARE OUR PRODUCTS MADE?

All our accessories are created out of high-quality bio calf leather, tanned and finished with 100% biodegradable products - we don’t use chrome nor any other hard metals throughout the process. Working with natural products, we want to encourage sustainability.

To increase the longevity of our products, we finish the leather with a water-repellent coating. This way, we invest in sophisticated and qualitative materials, helping you buy things that last.


BIO CALF LEATHER: WHAT IS IT?

Our bio leather is an alternative to traditional chromium leather, which is tanned using products that are harmful to the environment. Our partner uses advanced techniques to create our bio leather: it is produced with materials that are 100% biodegradable, without suffering any quality loss - which is often the case when using other organically tanned leather.

To produce the leather, the hides are tanned with chrome-free products. We work with small family businesses, adhering to the highest ecological and technical standards. They don’t use any polluting chemicals and instead work with tannins of trees, polymers and glutaric aldehyde. These are all natural resources, which don’t affect the environment.

During the manufacturing process, our partners reuse solid waste as fertiliser and reduce volatile compound emissions by drying the leather at room temperature.

When the tanning process is completed, the leather is finished with a water-repellent coating, creating a product suitable for rainy days.

Being colourfast and water-repellent, our bio calf leather shares similar properties with traditional leather. The big advantage is that it doesn’t have to pollute our planet.

Creating this type of leather is an expensive process, which might be a reason not every brand pursues to make use of it. As we truly value sustainability, we invest in the most environmentally friendly option possible, which is reflected in our pricing.



CONSCIOUS

We’re not only aiming to create visually appealing bags, but also highly value the practical aspect.

Lies Mertens started out as a brand creating handbags people can use for everyday life. Whether you’re on your way to work or having a drink with friends: the same bag can fulfill multiple purposes.

By adding different compartments to each bag, we provide enough space to store laptops, smartphones, chargers, keys and water bottles and create an easy way to retrieve all your stuff in a split second.
