I have a total of 100 of these display cards. 50 are brand new and still in packages. The others are loose. They have black velour on one side. Not sure of the size-maybe 42 or 43 mm, but they hold chips with a black ring around the chip like the one shown in the picture. Chip in picture is for sale in another post-just wanted to show size of display cards. $20 for all 100 plus shipping. Email if interested.
