I found these pics on Live-Journal that
ediktid posted. She's putting these MAC skin jewels up on E-bay, so I suggest you look on Ebay for the next few days. She said she paid $20 each for them (which personally I think is a rip off) but she said she got a really good deal. They are from the 2004 Holidazzle collection. I remember MAC sold a little stick on swarovski crystal design a while ago, that was about $20. I knew it was a rip off because I worked at a jewellery store and we sold a big pack of Swarovski stick on designs that came in a CD case for $25 CDN. You got WAY more crystals in the actual Swarovski pack than you did in the MAC pack. I think they are discontinued now, but if your interested I couldprobably track some down for you through my stores, or just check your local jewellery stores that sell Swarovski stuff. They were pretty sticky, I think I still might have some. I wore them for my birthday and other nights out at a club and they stuck on for close to a week. (Note they were individual crystals that came in a pattern. You could apply them seperatly or in the pattern. The ones the girl posted on LJ (pics below) are actually all one piece, you can't use just one of the crystals.
These are what the ones I have look like, mine are a different pattern though. They cam in a ton of diff patterns. They are going for pretty cheap on E-Bay, just type in Swarovski Crystal Tattoo into the search
***If you look on the left side of the package it shows all of the patterns of crystals that are included in the pack.
