Old stock Trumpers Limes ... with a little pigment settling under the cellophane packaging. Scent is still really good! Much akin to C&E West Indian Limes (no surprise). This is the Standard Company Limited formulation.
Just bought the Tatara Muramasa into my collection courtesy of @Keltoi (cheers Mark)
It is a fabulous razor for me in all respects. The short handle may not be for everyone but I have no problem with it at all.
I now have a redundant Tatara Masamune with an additional Nodachi head which I will BST soon.
