Per EBAY's policy the Caps Boxes that I am listing that originally held caps for cap guns or cap pistols are EMPTY.
The empty boxes will be flattened and mailed in a regular business envelope.
Please see my other listings.
I do combine lots for a reduction of shipping costs where feasible. If you win more than one lot, you can use the REQUEST TOTAL feature in the EBAY Cart, or simply pay EBAY's inflated S&H amount and I will refund the excess above what I would have put in a Combined Invoice.
