Our main raw material, cork is natural and eco-friendly. However, we always like to inform our users that if you take a look at the other materials that it gets combined with, they are not completely eco-friendly. But, we make sure they are not very harmful either. Here is the breakup. The backing of our materials is 15.5% Polyester / 29.5% Cotton / 55% Biodegradable Polyurethane. The dyes used in the cork are similar to those used in the leather sector and they fulfil European REACH standards, which are very strict. Also, the linings that are used in our products are 100% organic cotton. The packaging is created using dead stocks of cotton fabric, which would otherwise go to waste.So while every small bit of our product might not be 100% eco-friendly yet, if you do compare it with a similar product made out of synthetic leathers, it is significantly less harmful to the environment and a majority of what goes into it is bio-degradable. We at Arture do not claim to create products that are 100% eco-friendly, and we are very transparent about what goes into our products. We do however believe in improving products that already exist in the market by creating their sustainable version. That's why we chose wallets, to give you a better alternative to leather accessories. We are also always working to make our products even more sustainable and would love to hear any feedback that you think can help us in doing so.
