I have a Blythe Clone and just about everything is the same as a Takara Blythe. The eye chips are the same size but getting out the ones that came with the doll can be a pain. I used the glue stick method to get them out and then had to use a dremel tool to remove the plastic that was left behind.
There are a lot of tutorials on eye chip removal on you tube.

Wet sanding paper- the kind you dip in water with a little dish soap in it. I know I have some left somewhere, if I find it I'll let you know.
