Plugs for BC inflator/exhaust valve holes?

[Shinythings]

I have a Hollis SMS 100D (dual bladder). I took out the redundant bladder as I dive dry and have no need for it. Now I have two holes in the cordura wing outer shell. I'd like to put plugs in them to protect the bladder inside.

Does anyone have experience with this or recommendations for how to go about plugging the holes?

I'm hoping to make a trip to my local fastener supply to see what I can find.

call your hollis dealer, they'll have them since they ship on the Katana
