How to pack already graded/slabbed comic for signature 0

[colossus127]

Hey all, I hope this message finds everyone well! I apologize off the bat if this questions seems stupid or has been asked a ton of time, I did some pretty good searching and couldnt find any threads related to this so I figured id make my own.

 

The question is exactly what the title says, Iam sending one of my comics in to be signed with the CGC signature series but its already graded and slabbed and the instructions dont give much beyond making a "window bag" which I did research for and found out how to make. Do I need to do that still since its already slabbed? Would I need to make one that they are going to put it into and then have signed before they re slab it in the yellow holder?

 

Any info is much obliged!
