Read Thread: Do you ever send markers or ink?
I have on occasion sent markers or ink for postals that I wanted to ensure the right colors were used (with no issues). The ink/markers came back just as I sent them every time. If it doesn’t change the postage rate I don’t think it’s necessary to ask the group.
Send them in a baggie. :)
I'm intrigued that there are specific colors to use on your stamp. Luckily I'm in the ring and will get to see what you came up with. 🖍
