The "5" has a flat top to it. it doesn't angle up. There are also three parallel lines forming a corner. I tried to photograph it but no luck it appears only briefly before disappearing as the fluid evaporates. I don't fill a dish as it gives me a headache. I just put a couple drops in the recessed top of my gram scale which is black. here's a diagram as seen from the back of the stamp. The corner of the lines is rounded a bit.
