Fabulous markers! Couldn’t ask for anything better.
Only complaint is that copper is hard to see on light services but on dark services it pops!
A copper is a must.
Its simply a permanent marker. But it rights really smooth. Better than any sharpie. Small nib makes it pointless for the streets but I still find use’s for it.
It also says its refillable. But when it comes to refilling permanent markers, well, you got me.
