Comments Every now and again I compare this with other loupes, it is definitely the best and it's by Zeiss and it's all-plastic* which means it's very lightweight. * The lens is plastic too, but "plastic" sounds a bit downmarket so I prefer to say, "High-grade optical acrylic". Technical Magnification / lens size in mm: 10X13 Lens material: high-grade optical acrylic Lens type: Unknown, probably a triplet. Type: jewellers' loupe (small, pocket-size, folds into its metal casing) Origin / brand: genuine Zeiss by Carl Zeiss Vision Ltd (the old "West German" Zeiss, not to be confused with the lesser quality "East German" brand of Zeiss Jena). Casing: plastic Finish: cream and grey Presentation / extras: printed box Free Gift Zeiss loupes don't come with a case, they are supplied in a little polythene bag. That's because Zeiss are so 'famous' they don't need to give you anything extra. HOWEVER, we have come across some leather pouches that fit perfectly and will include one with your purchase.  Limited offer, because we only have a few pouches.  Further information Everything you need to know about magnifiers and magnification.
