Is a vinyl decal the same as a vinyl sticker?
This is where it gets fiddly! Yes and no depending on who you are talking to. In the trade these are two different things but as these products have moved online the lines have been blurred.
As decals are sticky there are a lot of people who would call them vinyl stickers. In fact there are lots of names for them including vinyl transfers, decal transfer, decal stickers, decal transfers, vinyl lettering, vinyl numbers, vinyl logos, etc.
