SMV Industries1FP-C Slow Vehicle Emblem

Shocked was I to find this safety triangle was PAPER! It has masking tape (on the public-view side) holding the reflective border on the interior triangle. It would flap in the wind. It would immediately be destroyed if in the rain. It is utterly useless. Even if I figure a way to affix it to something rigid, I don't know how to weatherproof it. Did I say worthless?

Just a sticker not a real sign
