I am presuming these are Australian "Presentation Packs"
Now you, as everyone else with Australian packs, are met with the decision to unpack, or keep as is.
Caveat: Aust Post suggest the packs are not suitable for long time preservation.
If you wish to display your stamps, then "Hagners" (Vario) pages are available at about $1 a page, or "Hingeless" stamp albums from "Seven Seas"
or print your own pages.
