It would be easy to make those Earthstar tags out
of .040 Polystyrene, too. Any place that sells sheets
of plastic (or a sign maker) would have it. It is thin
enough to cut with scissors, a utility knife, or a paper
cutter, and flexible enough for the job. Drill a 1/2" hole
in one end of a stack of labels, cut an angled slot into
the hole with whatever, good to go.

One can find them everywhere after election season.
Election signs are either ".040 styrene" or "Corex"
(corrugated plastic, looks like plastic cardboard),
screen printed by the hundreds or thousands.
You can write on even the inked parts with
waterproof black industrial marker or grease
pencil. (Recycling them for labels delays use
of landfill space, so it is a public service.)
