These chrome finish 21mm triplet jeweler's loupes (loops) offer 10x maginification which is more than enough for checking out specimens in the field. These pocket magnifiers fold up small to protect the lense and fit easily in pack or pocket. They can also be attached to a cord or chain and worn around the neck.
You can find higher quality loupes online, but many run $40 to $100+ each! Drop one of those in a stream and you'll wish you'd only spent $6.95 on one of ours... That said, our triplet loupes do everything you'd expect from a more expensive model at a tiny fraction of the cost.
