GOLDI FLORA OPTICS - MG 13B-5 - WATCHMAKER'S LOUPE - about 8x magnification - 25mm lens diameter - inclusive 1x MIKROFASERTUCH FREE - inclusive 1x credit card with (approximately 2.5x magnification) (office supplies & stationery)
As I said the watchmaker's loupe is in the "eye clamping ring" a little sharp and is not pleasant to use therefore. The zoom function is OK.
