These are Color-Bar Badge Holders! They have a colored bar on the top of the holder, and the rest is clear to display your card, which loads from the top. Attach a lanyard or badge reel with virtually any attachment, like this bulldog clip and vinyl strap. Or thread a chain in through the two small holes. Nicely display your ID card while adding a little extra flair and keeping it secure. You can get these in vertical or horizontal designs. Now I will note that these two designs load your card differently, one loading from the back, and the other the front. They are very flexible and light weight. They also come in several sizes and have an option for a cord. It’s really just a matching shoelace with an adjuster. And this here is the extra large holder.
