This is a very amusing salt and pepper shaker set, just like the Salt and Pepper Bots. Looks like real D-sized batteries, you might well get a good laugh from unsuspecting guests. Even the packaging it is sold in looks like those you would see for selling batteries.
The good thing about these shakers is that they also have a “power level” strip whereby you can monitor the amount of salt and pepper left in them. For those who like to collect salt and pepper shaker sets, these batteries will be a nice addition to the collection indeed.
