20" ESP Old School Polish Classic Ultra Thin 1556g is based on a previously made 20" 1546g. (It was sold right away but I "copied" the shape before I sent it.) 

Hand hammered bell, polished top. Even though is is ultra thin, it can handle some beating

The actual cymbal is demonstrated in the video recorded with beyer dynamic m160 (ribbon) microphones through zoom h6 to iphone.
