The Bausch and Lomb 20x Hastings Triplet Hand Lens, is a very specialized instrument, and we do not recommend it for the beginning naturalist. In any lens as the magnification increases, the diameter of the lens decreases. This triplet has a lens diameter of just 8.3mm. Includes soft storage pouch. Rim around lens is plastic; lens swings out of metal handle with loop for lanyard attachment.
