Abacus for the blind
I attended a school for the blind and used an abacus in math class.  I used it for years until it fell apart.  Happy to know Amazon had one listed.  It is just like the one I  am used to using.  it came quickly in the mail and is well made.  It seemed little too expensive with shipping, butI enjoy using it for my monthly accounts much more than an electronic calculator.
