CAUTION: Not to be used as a hard hat.
Now, where will you put it? On your hard hat?
Or maybe do a service to the folks around you, and put it on other items so they don't get confused:
Notebook? Not a hard hat.
Thermos? Not a hard hat.
Toolbox? Probably not a hard hat either.
Laptop? Definitely not a hard hat.
1 sticker per sheet. Available in 1, 5, and 10 sheet packs.
