As the name states GMK Denim features Denim theme which explains the colorway. Also if i think about Denim - then Jeans is the first thing which comes into my mind. I personally have never seen Jeans without leather patches and manufacturers logotypes. Thus GMK Denim does feature leather patch accent keys with logotypes of very well known and iconic brands (GMK and Cherry) related to our hobby.
So far GMK Denim offers only one base kit which is capable to cover most basic layouts.
The group buy for GMK Denim is hosted on Originativeco.com and the price is 129$ for the base kit US GB PAGE EU GB PAGE ASIA GB PAGE
