Did this slacker ordered me case for 5.99, because many other NoName or at least less well-known brands are already gladly times more expensive. Find it also makes a better impression than other "low-case". In my class I have this case of Herlitz repeatedly seen in different colors, some use it for some time so hälts probably awhile :-) In the power perfectly fits my calculator Casio FX911ES and in the main pocket is enough space for various pins, Geodreick, Tipex etc. Those looking for a low-priced case is well served with this Herlitz!
