Thin Plastic Sleeve
The signs look great and we got them very quickly! Just make sure you are aware they are the kind of signs that are thin plastic sleeves and not a plastic covered foam board so you are not surprised when you get them. Be very careful when putting them on the metal so they don't split and I would have some packing tape handy if they do. I had to give them three stars but it would be more like 3.5 because I think the price is a little high for being the plastic sleeves.
