WHY ARE OUR PRODUCTS FREE?
Since there's no better way for brand marketing than the word of mouth (that's you), we prefer giving a limited amount of products for free to people like you, instead of investing in expensive and ineffective brand advertising.
If you like the product you will wear it and recommend us to your friends. When asked by people where you got your products, we're sure you will recommend us again. That's the best advertising for us. This is a win-win situation!
