One mouse has a harp.  This mouse has a halo and stands just over 2 1/4 inches tall.  Is nearly 1 3/4 inches from ear to ear and is 1 1/2 inches from toe to tail.

Another mouse with its halo seems to be singing.  This one is just under 2 1/4 inches tall.  Again almost 1 3/4 inches ear to ear and 1 5/8 inches toe to tail.

Then the third mouse....seems to be wondering what happened and why they have a halo in their hands.  This one is just under 2 1/4 inches tall.  With the same ear span of nearly 1 3/4 inches.  The length on this one is nearly 2 inches from holding halo to tail.

All 3 mice have stickers from Korea, they also have black eyes.  From what I have read that means they are 1970s, pre-1982.

I found no chips, but please look at all the photos.
