This is a 3M™ Security/Privacy Filter for 21.5-inch monitors, 16:9, model PF215W9B. I am getting rid of my computer monitor and no longer need this. Please read the following notes carefully before considering a purchase. [Notes] ・There are no stickers to attach the filter to the screen. Only what is shown in the first photo is included. ・As shown in the second photo, there is a small chip on the edge. There is no problem with viewing the screen, but please refrain from purchasing if you are concerned. ・There is no original box. I will ship it in recycled packaging from my home. ・This is a used item that has been used for nearly 2 years. There are no scratches that interfere with viewing the screen, but if you are concerned, please use the packaging materials I sent and return it in the same condition as when it was shipped.
