You get the earclips with 7 different pieces to put on them, you can put 1 or 2 pieces maximum on there and make many combinations. How do they work? You simply have to GENTLY(!) push/pull them over the small diamond. It's at own risk, but me or my friends didn't have any problem with them. For size reference the card is 12x15cm and the green clips are 4cm diameter. None of the other parts have a diameter larger than 4cm. The cards are in good condition except for some small cringes or spots on some of them. Earclips are in excellent condition. They come out of an old stock of 50-60's jewelry
