An Gilded magic wardrobe flatpack can be made at a workbench (Bench with lathe only) in the workshop of a player-owned house. Like when making the normal Gilded magic wardrobe, this requires 87 Construction, uses 4 mahogany planks, 1 gold leaf and gives 860 experience. The flatpack can then be used on a magic wardrobe hotspot in a Costume room, either in building mode or not. This requires no Construction level and gives no experience.
The cost of making and selling a Gilded magic wardrobe flatpack from scratch gives a profit of: -94,970
After completing the hard Fremennik Tasks, they can also be traded to Advisor Ghrim in exchange for ? coins being added to your kingdom's coffers in Miscellania. See Flatpack: Miscellania reselling for details.
See Magic wardrobe for a list of armours that can be stored.
