I need the plastic cover that goes over the mini casio calculator hr-8tm 12 digit

I would contact INVISI SHIELD , search for them on Google. this company is great I got the shield for my Iphone and they use the same grade plastic that they use on helicopter blades and its so strong you can rub your keys , a knife and many other coins / items and it wont ever scratch your product. These guys have almost any type of cover for any product and they also custom make them and you cant even notice any bulkyness or change on the look of your product, hardly even visible that you have a cover. Hope my answer gets you closer to a solution. Please Help rate me if I helped you out or not I am new but a very good tech.
