Slide Loupe Photo Loupe The loupe is surrounded by black on all four sides, allowing you to view negatives, positives, slides, etc. by placing a light box or similar device underneath. To prevent scratches, soft, leather-like tape is applied to three sides of the bottom. This item has a luxurious feel, so what do you think? The manufacturer is unknown. Size: Longest side, bottom: 6 cm x 8 cm Height (from the bottom to the highest point): 6.5 cm The film canister in the photo is for size reference only and is not included with the product. Magnification is not specified and is unknown. Focus adjustment is possible. What do you think? Thank you.
