In the 90s, a couple passionate about making clothes create denim models for women where everything is handmade from creation to manufacturing. They innovate by developing materials that are very soft and comfortable to wear. They open a first sewing workshop in Paris. The quality of the handmade, the finishing details and the extreme comfort provided to the pieces allow them to quickly stand out compared to other brands on the market. The two founders then extended their distribution throughout Europe through resellers.

In the 2000s, the case is transmitted to 3 children who decide to develop new materials and finishes to expand the ranges and offer a wider choice of models. They continue their parents' project, constantly developing ideas “innovative recipes” combination of materials, making denim softer and more comfortable. They develop jeans that are both very trendy and unrivaled in comfort.

In 2006, the 3 children decide to give their project a name. They want a name that is easy to remember and that shakes up conventions a little, capable of making an impression.

It will be Toxic3.

To be three, it was more than just a number to them; it was a symbol of strength and complementarity, each bringing their unique perspective to the project. But they also saw in this "3" a deeper and more subtle meaning: in English, "three" can sound like "free" (free). This resemblance inspired them to create a brand toxic-free, free from compromise and committed to authentic values.
