Vintage Letter Opener Comoy's of London Gold Tone 7 1/4" Made in Japan in original box

Very pretty vintage letter opener. No tarnishing, no major scratches. Appears unused or if used, very little. The handle has ridges. Made in Japan for Comoy's of London. 
I am uncertain of the material of the letter opener. Perhaps brass - it is not magnetic and has a gold color. 

I do my best to give honest and complete information and to disclose any observed flaws. Please contact me if you have any questions.

With kind regards,
Margie from Raggedydoll's Neighborhood
