Our universal window tint decal sheets are made the same way as our other window decals. Clear 3M vinyl with your choice of medium and dark tint. Measure a window, cut out a rectangle or square from the sheet and simply squeegee it on with your thumb. Trim the edges with an Xacto knife and you’re all set! Each sheet is approximately 4mil (much thicker and more durable than rtr window decals) and measures 11” x 10”.
