Sealing Wax question

I got mine in AC Moore and there are 4 sticks of wax in the box. I did 55 invites and have 1 1/2 left over. So I'm guessing you might need 2 boxes from them.

Don't drip the wax too heavy for the seals because if the seal is too high and won't go thru the post office slot tester, you will have to pay xtra postage for manual processing.
