This is an inert replica of an Atlas delay blasting cap. Also included is a reproduction copy of an Atlas ad for delay blasting caps, printed on high quality vintage style paper. The copper tubing is hollow and inert. Great for display purposes.

If you are purchasing multiple items and want combined shipping, don't pay until I send you a revised invoice, or I can just refund any overcharge after the purchase (ebay often overcharges for shipping on multiple items).
