Three mislabeled boxes of pencils and erasers

[dontdisturbmycircles]

Interesting puzzle I came across today, not too tough, but rewarding in the end.

There are three containers labeled "pencils," "erasers," and "pencils and erasers". Each of these labels is incorrect. You may select only one item from one box. (No feeling around/peeking permitted.) How can you label each box correctly?

Sorry if it has been posted already.
