I would not store Aqua regia in sealed container it could explode, as gases break down.
I would not put peroxide in it for storage, although it will help to keep the NO2 from gassig out if very pure,
if you do not have proper bottles to store your nitric in, you can use a bottle clear with a small lid like a gallon jug, make a teflon cork , or use teflon tape and wrap lid well ect, store it in card board box (I use the styrofoam pakage my bottle came in) to protect it from light,
not in any place than can get broken or where some child may get ahold of it, or animal ect may break it,
I would never store these things very long, it is easier to make a batch as needed,
I do not store these inside they will destroy your stuff
or can be bad for your health.
I will check them to see if they are building pressure by cracking open the lid every so often,
Viacin you might consider building or getting a wood cabnet or metal with a lock storing outside ( I use an old stainless steel cart with plastic pans to store my chemicals out side, again i would not store these acids if you dont need to.also always lable anything you do store it helps later from making costly and dangerous mistakes.
if the acids are weak they store a little easier
these are just my opinions till I learn different
That would be quite, erm, impossible
