As pure of form as it gets, and clad in the most perfect old blue paint, I do believe this is my favorite pencil box I've had, and I have a special love for pencil boxes.  The second photo shows the angled cuts of the box and lid ends--to my eye a very beautiful thing as one slides across the other. With what looks like an well worn old paper label on the short side at that end, and a rivet at the other allowing the lid to turn 360s degrees. Found in Mid Coast Maine, late-ish 19th c. I would think, completely lovely.

 7 1/2" x 2 x 5/8". Excellent condition, perfectly aged.
