Showa Retro SHARP ELSI MATE EL-8111 Calculator Working condition confirmed. Uses 4 AA batteries *Batteries not included. It's old, so there is some discoloration and dirt, but I think it's a rare item that you don't see very often these days. The instruction manual is included, but as shown in the photos, there is dirt, discoloration, and torn pages. Please understand that this is a used item before considering a purchase.
