Perfect pens
Refyne are my favorite of all pens, I bought an EP1 when I bought these gold parts. The EP one I bought is gun metal I thought it would look really nice with the gold screws and the gold top. Refyne pens are top notch, and work very well for me. They come with an excellent cartridge too.

Such a stud!
I lost a thumb stud and was slightly devastated when I couldn't find it. The EP1 is such a great pen that I, thankfully own two. Replacement stud + an extra arrived quickly and was installed with blue thread lock. I'm back in business and rocking copper on Ti.
