Imprint is 100 / on the other side is a vertical slit
color is a dark blue (kinda grey/blue)
shape is flat oval

blister pack reads "Trate Tab" ( the blister pack is only 2 pills so the rest of the lettering is missing, so all I can read is "... TRATE TAB"
Under that reads "... RA TABLET" again the beginning of the lettering is missing. Blister pack also says "NIZAGA"
