This is a good deal for a set of lightweight replacement or extra lens caps — this is a set of three and each includes a tether (the tether fits around my lens and doesn't cover the markings + The disk has a small pad that attaches to the cap adheres; simply remove the paper wrapper and stick on). I have two older Pentax film cameras (I think they're considered dated now — sounds better than dated anyway). It's actually the same model, one belonged to my father and I later chose the same one when I first became interested in black and white photography. The original lens cap on one of them was lost long ago, but the camera is stored in one of these matching cases so the lens was protected. Unfortunately this case is now falling apart and I found this kit which seemed perfect for my needs. Most lenses are marked with a Chi symbol followed by a number denoting the diameter of the lens (as shown on the pictures in the product description) but not all lenses have this and as it turns out mine don't. It's possible to measure them with a metric ruler or tape measure, but being an amateur photographer I wanted to be absolutely sure, so I looked online for my 50mm lens. It turned out to be quite popular for the time (30+ years ago) and I found a website that showed all the specs so I was sure to order the 49mm version. These caps aren't as sturdy as the original caps — they're thin and light, but they're easy to position (simply squeeze the sliders on each side to attach or remove). They fit securely on my lenses, don't come off easily and I feel the glass is well protected. I really like the leash as I always lose lens caps they don't have (I take them off and put them in my bag or put them down and forget where). I really only ordered this set for the lens caps and I really like that there are three of them so I have extras. The microfiber cleaning cloths are also of very good quality. There are three and each is wrapped in a separate foil pack. The squares are a good size (approx 6" x 6") and are very fine, very soft and silky. They are a welcome addition to my camera accessory kit. The current price of $14.99 seems very reasonable to me.
