Good cases

Perfect fit for Texas Instruments BAII Plus Professional. Makes it easy to keep instructions with calculator for easy reference.

The attached photo is what happens when you don’t keep your beloved financial calculator in a hard case. What’s hilarious to me, is my scientific calculator which costs a fraction comes with a hard plastic sleeve. My HP financial calculator came in a faux leather slip case. not much protection even for the casual business user! Anyways spend some money and buy this case. I have discounted a star because it is not the absolute hardest case available. It does have some flex. So five stars goes to the case that absolutely protects your Calculator. But, very good quality for the money. So yes, I recommend.Update: Still works great!

My case actually has more of a soft velvet like liner rather than the terry cloth shown in the Amazon picture. It's nice. Great zipper. The mesh pocket side is nice and roomy. My HP 10BII+ and HP 30B fit perfectly. I also tried a HP 12C and there was room on both ends but the elastic strap holds it well, no movement. Because the HP 12C fits it will also hold all the other "Voyager" style HP calculators: HP-10C, HP-11C, HP-12C Platinum, HP-15C, HP-16C. I also tried a 30 year old HP 17BII and it fits but quite snugly. Because the 17BII fit is will also hold all the other "Pioneer" style HP calculators: HP-10B, HP-10BII, HP-14B, HP-17B, HP-17BII, HP-20S, HP-21S, HP-22S, HP-27S, HP-32S, HP-32SII, HP-42S. The HP 35S is too tall for this case. My hand strap is too small for my fat hand and is sewn crooked but is sturdy anyways. As an experiment I put the HP 12C (a thick calculator) in the mesh side and the HP 10BII+ (a thin calculator) face down in the elastic strap side and was still just able to get the zipper closed.

I bought these cases for my old HP RPN calculators as the original fake leather sleeves were falling apart after 20 years. I originally bought the smallest size case, but the calculators were too long to properly fit inside even though the case length was more than the length of the calculator.After returning my original purchase and sizing up in my next one, I can confidently say that the case advertised for the Casio fx-300ES PLUS 2 is nearly perfect fit for the HP 33s and 35s.The cases seem durable and made of material that won’t flake apart with time. The cases are structurally sound enough that they won’t collapse with the expected forces in a backpack or other school bag.I recommend.

My HB10bII calculator is from around 2010. I used it extensively for multiple years, and then it sat in a drawer somewhere for many more years. Recently I decided to take it out, and found that the original calculator sleeve had started to disintegrate. It was dropping little pieces all over the place...so it was time for a replacement case. This one is much nicer than the sleeve it came in, and I feel good knowing that it will be protected!

Nice case. Flexible, yet somewhat rigid. Soft liner and elastic strap to keep your calculator secure. Nice mesh pocket on the inside front cover for pens, notepad, etc. Comes with a handy wrist strap.
