Gorgeous!
They are also very hard to find complete and with their ribbons. I think you will find their ribbons will push them even higher. I would be tempted to auction them. I know I have been after them loose for ages and I am sure you will get lots of accessory collectors in addition to me happy to bid just for the ribbons alone.
Twinkler - $12 + $12 for ribbon
Star Hopper - $12-14 + $15 for ribbon
Star Dancer - $10 + $22 for the ribbon
Napper - $14-15 + $15 for the ribbon
