A gilded cape rack 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 cape rack, this requires 81 Construction, uses 4 mahogany planks, 1 gold leaf and gives 860 experience. The flatpack can then be used on a cape rack 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 cape rack flatpack from scratch gives a profit of: -42,849
After completing the hard Fremennik Tasks, they can also be traded to Advisor Ghrim in exchange for 13,270 coins being added to your kingdom's coffers in Miscellania. See Flatpack: Miscellania reselling for details.
