I had a pen I ordered early this year to write on the plastic tags and the ink would spill out and get on me and it came off those tags. It was garbage.

So, at the Mega Store there was one that the customers swore by didn’t come off even in the rain, so I ordered that one and have it. I’ll use it and see what happens.

Try Sharpie marker black pens. If you write it on plastic, it will last at least through one season out in the weather. The ink IS NOT water soluble, and if you want to wash it off anything, you will have to use alcohol or other solvent.

I cut up styrofoam plates to use as stakes to identify plants. (I feed my kittehs canned food on these, so there is always a supply around.)
