Storage (tubes or wallets) for fractional Britannia collection

[breaktwister]

I've been picking up the 1/10oz or 1/4oz gold proof Britannias.  Keeping them in the royal mint boxes is becoming a pain so I'd like to store the boxes away and store/display the coins in a neater manner.  I have seen some nice display type wallets in various coin related youtube vids but as I have a mix of 1/10 and 1/4 sizes I am unsure what to look for that will accommodate a series consisting of both.  Alternatively I am happy to put them in tubes until I fill in more gaps in the series (about half done atm), I guess its the airtite tubes if going down this route. Does anyone know what sizes I would need so as to fit the mint capsule in?  All suggestions welcomed.

If they are proofs then I'd leave them alone

Maybe Morezone knows what you could transfer the capsuled coins into (display box?)

Yes, happy to keep them in the original capsules but store the boxes and certs away

I think somebody posted somewhere on here recently that they were having trouble finding trays/boxes that hold the RM caps.  I can't remember who it was.
