1080 Poison Sign
1080 Poison Sign is sold in white 200gsm thin cardboard. This material is mildly resistant to being wet for a short time. You can, of course, cover the sign in cling wrap or put it inside some clear plastic. Signs are usually stapled or wired on. For a more permanent sign, choose Corflute or other.
We only sell the cardboard signs in lots of eight and in one size only, whereas the plastic and metal signs are in quantities of one and up.
