The new FBS signs are made of plastic and have an adhesive film on the back. All FBS Mini signs are made in the scale of 1:12 trying to bring some realism to your fingerboard spot.
The adhesive foil on the back is extremely strong and sticks to pretty much all smooth surfaces. If you want to remove the sign again, then remove only the corners of the protective film and leave the remaining protective film on the adhesive surface.
1x FBS Mini Sign 'EMERGENCY EXIT'.
