Basic Calculators $1 each (Texas Instruments TI-10 $5)

The basic calculators are $1 each and the Texas Instruments TI-10 is $5. I wiped them with alcohol wipes for extra hygiene. The 3rd calculator (with the binder holes) has no battery inside (battery died so I tossed it out). It uses an LR1130 battery, otherwise works fine and has the convenience of attaching to the metal brackets in a binder. TI-10 comes with a face cover. Every calculator’s battery is replaceable, you just need a small screwdriver to get into it. Feel free to check out my profile to see if anything else interests you.
