Porro Abbes are small glass prisms used extensively by Uncle Sam as image-erecting systems in small optical instruments of the World War II era. They look like two small right angle prisms cemented together, but are actually made from one piece of glass. Ours have entrance faces about 5/16" square, giving them an overall length of 11/16". In final use, porro abbes would have received two facefuls of silver or aluminum to enhance reflectivity from key surfaces, but ours are plain. . . and they do have small edge chips which your fussy Uncle found offensive, and which you will barely notice in your rapture over porro abbes. Enough history. The pure bubble-free optical glass renders these prisms optical jewels suitable for window sills, earrings, and general spectral fascination. No passport needed.

WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
When you peer through your magnifying glass at this specimen, or focus your microscope on it, even at the lower magnifications which work best, you're looking at one big bug. Make that (4) big bugs. The insects are real, encased in clear acrylic blocks 1-3/4" x 1-1/4" x up to 11/16" thick, and ready for inspection. Set 1 includes a scorpion, giant ant, wasp and a flower bug. Set 2 is a cricket, locust, yellow leaf beetle, and crab. No, not a crab louse or a crab spider, but definitely a crab ugly….

Small enough to fit into the belt-mounted black canvas carrying case (4-3/8" x 3" x 1" thick), but they open up to be plenty big for most binocular needs. These 10X25 binocs have glare-reducing coated lenses, a thin neck-strap, adjustable focus, water-resistant and easy-to-hold rubber skin, rubber eyecups and fine-tuning for the right eye.

Two versions of teeny-weeny-tiny microscopes. Cute, but not toys. Both deliver 45X in a miniscule body with a 1/4” eyepiece. The non-illuminated version is 1-3/8” tall x 9/16” dia. The UV-illuminated version is 1-1/2" long x 1/2" dia with a swiveling, removable 1" long x 1/2" dia dual-LED ultraviolet light (dandy for checking IDs) attached to its side. Powered by a trio of button-cell batteries that are included. Both scopes come in equally teeny black fake leatherette-like pouches.

Everything about this magnifying glass is big. Really big. Hence the name. A approx 6" dia lens provides 2x magnification. The frame is metal, and the handle is 6" long and made of metal. Ostensibly handheld, but with a nearly-inch-thick glass lens, it's heavy enough to give your lower arm muscles a big workout.
