Clarinet (small) Cufflinks

I'm working on a full orchestra for the website! Here's another addition.

These clarinet cufflinks are smaller than the other clarinet cufflinks we have online. I am presuming they are therefore the E♭Clarinet, but can't be sure.

Dimensions (LxWxH): 27mm x 5mm x 5mm (approx.)

Weight per cufflink: approx. 4g (light)
