Recent days me and my friend had done some research to color the titanium key and finally things have been going well
,u can see the pic on the bottom, the process of making this kind of titanium key ensured that the color of each titanium key is random,which means that every colorful titanium key have its single surface,we named our new titanium hulk key
the classical titanium hulk key.Now our classical hulk key is still under our development,we give the pic of our experiments to share with GHers!
