These are new, stainless steel salt and pepper grinders from Modern Home that are each powered by 4 1.5 volt AA batteries. (Be sure to use rechargeables!) These were a gift but they don't match much in our kitchen but maybe it would be a better match for yours. These come with the instructions and a 1 year warranty that was never registered but likely will be honored if you apply for it.
I'll ship if you're willing to pay for it or swing by Wrigleyville or the loop and pick them up for free. These are listed in a few other places so I reserve the right to end this listing without notice... Get'm while you can! Please let me know if there's any questions about this item and I'll get back to you within an hour.
