i found these pills that look like a brown mm candy basically the same size design or shape as an m&M but the color brown is like a shade and half lighter but still dark. They look like they have a candy coating or shell. one side is blank and the other is S12 in white like paint like how they add the m&m logo or stamp on their csandy. i found them in my sons room and have been checking for over a week online with no luck. I remember seeing them last summer in his room too and he told me they were a new mm with logo and i believed him but to still have them a year later? And they definitely not mms! Can anyone please tell me what this is?Thanks
