I'm looking at the basic assembly package page and the steps to follow and it says to ask the notary for certified copies of the package, 3 copies are suggested. I have a question. What are those copies for? Are they related to the full body armor package?

Step Four:

Once you have compiled all of these documents search for the notary page on our website.
Contact the notary of your choice. And set up an appointment to have him notarize these
documents. The procedures are listed on that page so just follow those. When you are
making this appointment please also advise the notary that you were going to need a few certified copies of these documents. I would suggest making three certified copies.
