Does Dad do puzzles? One of these refillable puzzle pencils would make a great Father's Day present--choose from crossword or sudoku models. It comes in a great presentation box with extra lead, and (not that he'll need them) extra erasers.
This refillable golf pencil set may just be the perfect Father's Day gift for a dad who golfs. It comes with three tees, a ball marker, and one refillable/retractable lead golf pencil with plenty of extra lead. We have it in green (pictured in the center on the right).
