From what I could tell visually, this is an exact replica of the 35mm negative holder that came with my Epson V600 Scanner. I ordered a back-up from Amazon because these are made of flimsy light-weight plastic and are pretty fragile to handle when using them. I want a back-up as a precaution. When this one arrived from Amazon in a bubble envelope, it was broken. So I have requested a refund from Amazon, and will order it again.
