Rare Vintage Casio Micro - Mini Calculator near mint works perfect with case

Description

for your consideration  is a really nice Rare  Vintage Casio Micro - mini Calculator in its original case ..and works perfectly
it has not been used very much going by the nice condition it is in ...and it  is a very nice collectors piece for someone who likes vintage electronics ..i believe it to be a very early model with the on off switch on the side ..i seen similar ones with the switch on top with the pad ..but this one is on the side so i think it is the first generation and changed the switch position later models  ..
i just put in a new battery and a extra one will be included
