Where to buy cheap nail polish (or other idea)
I live in a fairly rural area and I need to buy something
I can put on my jump standards to mark particular holes
so volunteers can quickly move the cups to the correct
height during competition. I thought I would get a
couple colors of nail polish and put a dot by each correct
hole on the standard, one color for lowest level, a different
color for intermediate, another for highest.
Trouble is, I don't use nail polish and have not bought any
for decades. We have a Walgreen and a Walmart and a
couple dollar stores in town. Where will I find colors of
nail polish cheap? Or can you suggest a better way to
mark the standards? I do want some sort of marking that
can mostly be removed after the competition, either with
chemicals or by sanding/scraping/peeling.
