I didn't buy it, it was a wedding gift...in 1967 and still in use, at least once a week.
A Tala box grater-no, it doesn't grate boxes but is box shaped. It has different grades of size of grater, for cheese, nutmeg, fruit zest etc, and my kids loved the slicer side which enabled slices of cheese of uniform thickness, makes a great sandwich and a better toasted sandwich.
Sadly, I wrote to Tala to thank them for this wonderful long-serving invention and received no reply. Awww.
