What size battery 100 yrs. pin?

[Gator Kate]

Hi there,
My nieces have the pins that flash at various attractions, but the batteries died. I'm meeting them at WDW next week and wanted to bring replacements to them. Anyone know offhand what size they take? I'm assuming it's a watch/calculator type. Thanks in advance!

I think it is CR2032. I hope it is, that is what I bought last night for mine!

You should be able to find them with all the other watch batteries.
