Can't we nugde Lumintop to make a Copper IYP365 ?? (penlight)

Hello! I was wondering why there is no copper version of this pretty penlight, since we have aluminium, brass, and titanium versions.
So, I decided to ask here, can someone propose this to Lumintop? Perhaps a group buy?
Thanks !

Obs: in high CRI nichia flavor, of course! :smiley:

Hopefully the tailcap will last as long as the led’s rated lifetime
