I have come into some great boxes that were used once to transport some books. They would be great to ship glass or porcelain multipart insulators, either as the inner or outer box. They are U-Line boxes model no. S-4731* with inside dimensions of 18" x 18" x 18", double wall construction, 275 lb. test.

If you were to buy them new at U-Line, you would be paying $3.50 per box with a minimum purchase quantity of 25 boxes plus shipping.

I have ten (10) once-use boxes that I am offering for $2.00 each with free delivery to the South Lake Tahoe Insulator Tailgater in July or the Colorado Springs National same month.
