Are the buttons plastic or rubber, and can you store your own formulas?

Buttons are plastic, and you can't store your own formulas in it, for that you need a programmable calculator.

The buttons are plastic and I am sorry, I don't know if you can store your own formulas.

The case has two layers. The first later that goes on is rubber. Then a plastic piece clips on to lock it on securely. The rubber at the corners is exposed, as well as the areas where the buttons are.

The buttns work perfectly and are soft rubber. The buttons are surrounded by the second hard plastic skin but are easy to get to.

Combination of plastic & rubber. My hands are big and the case feels secure in my grip .

I believe they are plastic or coated making in look like metal, the buttons can easily be replaced, I've had mine in place 6+ months and it still looks like it did when I installed it.

No they are plastic like a regular PC keyboard. There is no mouse function though.

They are plastic, but not the same feel as cheap plastic, but have a little give that is comfortable to push. The buttons are slightly raised in the middle, but are easy to press and feel nice.

the buttons are rubber-coated over plastic, to be exact. If your concern is finger slippage while dialing, fear not - the friction supplied by the rubberized button is secure. BUT, bear in mind this is a bare-bones, land-line phone. Nothing about it screams quality.

No, It is more like rubber. It protects the back and the sides, and has a small rise in the front, but it is very small. I like it because it makes it easy to operate the buttons easily on the sides. I had a hard case before but had to push very hard to operate the side buttons. I hope this helps you. Robert

Buttons are made of brass and available in the brass color OR satin nickel finish...this is the right one for you.

The colored part is a hard plastic, while the black is a rigid polymer that works will the the buttons and to pad the inside of the case.

They are hard plastic squares. My students love playing with them for free choice activities, and I can use them for a variety of math applications.

They are harder plastic. Definitely not silicone. I think the keyboard has a nice feel.

It's textured plastic with rubber around the edge on top and where the buttons are.

It is a thick, hard plastic with a softer liner around the edge that is made for a better grip. There are openings for the buttons.

I don't know. I bought this press for a gift and can't remember if there were plastic parts in the inside.

The two metal finish buttons are plastic with a thin metal veneer on them. The white button is plastic. I wouldn't think you could buy replacement buttons. We've used the brushed metal one for a while now with no signs of wear.
