In Singapore where it rains a lot, I have used the cut up Venetian blinds
previously but eventually they will rust from the edges even under the baked
on enamelling. Pencil works well on them.
I have since begun using simple plastic knives ; the kind that were used on
airlines when they feared hijackings and for children's parties. They can be
bought in quantity very cheaply.

It is an easy way , just stick the operational knife part in the soil/pot
using the handle as the reader part.
I inscribe the name in pencil as indelible ink fades in our strong sunlight.
Eventually algae will form on the knife and the pencil marking will not be
so clear, but it will suffice if one does not want to use an expensive
proprietary system.
Algae also forms on aluminium strips.

Best wishes from a gardener from Singapore
