Hey there :)
I found an dupe for the infamous Nufu.oh No. 51 and thought to share it with you. It's from an austrian/german brand called glam nails. I believe it's from an LE but haven't found an official site and the label is not really readable.
The downside: a bottle only holds 5ml and seems to be as sheer as the original "sister"
Let's move on to the pics (yeah, I was lazy to re-watermark them ;)) :
