Fluorescent Light Covers

Set of 4 Used, but in wonderful condition and ready for a new classroom. They have a couple of VERY light marks on them (see pictures, they are difficult to find). These are labeled to cover 2 x 4 lights, but they are sized a tad smaller. They each have 8 super strong magnets that hold tightly. I will send them in a box labeled for a grey set. I didn’t hold onto the blue box. *They are made of flame retardant material!
