I have a few Chibi Hydes and Yukihiros for sale. They are from Le-Ciel fan club merch... Grand Cross Tour 1999. Originally, they were sold as cell phone straps, but somehow, I found a bunch that didn't make it to final product - they are just the chibi part, with no strap, and no holes in the head or anything. Just cute lil' Haidos and Yukkies!
Here's a pic of them - item #191.
There are three on eBay.
You may also contact me directly about them. They are 1 1/2 inches tall, plastic, and cute as a button. I found them in a gift store toy barrel!
