Offered here is a set of four (4) batteries designed to simulate the original Z8 penlight cells made by Zenith in the early 60’s. These batteries are actually modern alkaline AA cells that have been wrapped in a sleeve which replicates the early batteries. They make a great display, plus they have a full charge so they can be used until they are depleted. They will arrive to you in a nice plastic holder. Below is a picture that shows the impact of adding these to your boxed set. Cool.
