A pocket magnifier makes a great traveling companion! Shop our collection and get a great compact magnifier. Pocket magnifiers include wallet magnifiers and credit card magnifiers. A pocket magnifier is great if you need something lightweight and small enough to fit in a pocket or handbag. A pocket magnifier with a magnification of at least 5x or greater, is great for hobbies such as coin collecting, stamp collecting and antiquing. You can take your pocket magnifier with you to trade shows, shops, and garage sales. As with any magnifier, bear in mind that as magnification power increases, the magnifier's lens size will decrease. As a result a 10x or higher power magnifier will have a lens size of less than one inch in diameter.
