This listing is for 12 additional LR41 batteries. Each earring takes 3 LR41 batteries to charge. This listing is for 2 extra sets for each earring.

You are welcome to buy replacement batteries on your own, They are cheaper that way- but its nice to have an extra set on hand as soon as you get your earrings!
