Super Strong White Flexible Vinyl Magnet Roll - 2 ft x 25 ft x 30 mil - Commercial Inkjet Printable for Crafts, DIY Projects, Signs & Refrigerator Organization

Not very magnetic need to tapeIt does come in a roll but, takes a little time to make flat. I roll it out and add heavy flat objects (books) on top for an hour.Bought to cover sheet metal HVAC vents not even close to sticking. I tried and stuck the sheet and some allitional neodinum maginets I had.... no go. the problem is the sheet is to heavy and not magnetic enough. So I already cut the sheet I don't know if i should return, what a waste of money.Not even close to super strong, they should not have that in the description. Extremely disappointed!Purchased this to cover AC vents to redirect air more efficiently. Verified vents were magnetic prior to ordering. Magnetic side is very weak and doesn’t grip at all. It did however to the side of a toolbox. It would work as a car sign if needed. First delivery was lost, took company 3 weeks to ship replacement which came in damaged packaging. Guess I have to eat the cost since it’s been cut for installation.You should roll this the other direction. It needs to be flattened and rolled backwards to really have the best effect. It cuts OK but the white mars very easily. It will work for my intended purpose but I think there is better stuff out there. I suggest you keep looking.This was not magnetic at all. I tried to use for car door magnets, nothing.I cut a smaller piece to test on my fridge, nothing.Don't waste your moneyThe magnetic adhesion this product offers wasn't even enough to overcome the curve from how it was stored and shipped in a rolled up way. Even on a completely flat and magnetic surface. It is in no way "super-strong".The only way I'd see this product being useful is if you were going to cut it into 1 inch squares or smaller.Don't buy if you're looking to use it any way larger than that.
