PioneerCase

Although the slot position is in accordance with the calculator when dealing with the HP15C pouch (which I had as well), this is not the same story for the Pioneer calculator. The original pouch have the slots on the side for one reason : to be able to extract correctly and safely the calculator. With this pouch, the slots are on the front and on the back, and this is really difficult to extract the calculator from the pouch.
Otherwise this is a really nice finish product.

This case fits my HP42S like a glove! It’s easier to get on and off than the plastic cover HP supplied, and is wonderful to hold.
