An Teak clock flatpack can be made at a workbench (Steel framed bench or better) in the workshop of a player-owned house. Like when making the normal Teak clock, this requires 55 Construction, uses 2 teak planks, 1 clockwork and gives 202 experience. The flatpack can then be used on a clock hotspot in a Bedroom, either in building mode or not. This requires no Construction level and gives no experience.
The cost of making and selling a Teak clock flatpack from scratch gives a profit of: -3,661
