11CM X 9CM Pack of 10 Self Adhesive Caution Hot Surface Stickers, Caution Hot Surface Sign Vinyl Stickers.

You get 10 as stated and they are indeed 11x9 cm. I stuck one on a plastic surface and it stuck easily and quickly. They are vinyl so do not tear easily and should be OK to wipe clean.This is not a criticism of the product, but it's perhaps worth saying that it's necessary to consider what size of sign you need based on the size of the hot surface and from where people will be viewing the sign so that it is prominent enough to be seen in good time. Signs I've seen for this purpose elsewhere vary from A5 - A3 and these stickers are clearly a bit smaller than even A5.But if these are a suitable size for your need, I can recommend as they are clear and bright and good value (provided you need that many of course :-) )

These stickers are made from thin vinyl and stick well to non-porous surfaces.Just make sure to clean the surface and allow to dry before applying.Not recommended for use on porous surfaces, but smooth clean surfaces, they work fine.
