Item:Customization Kit (New Horizons)
Customization Kits are items introduced in Animal Crossing: New Horizons that are unlocked by completing Tom Nook's Workshop on customization. Once unlocked, they can be used to alter the appearance of various compatible furniture items. This ranges from patterns on fabric to the color of the body. Once Nook's Cranny is upgraded, the Customization Kit is sold both in singles or in bulk. Additionally, there is a type of Customization Kit known as the Customizable Phone Case Kit obtainable from the Nook Stop for 1,800 Nook Miles which is used to alter the look of the player's NookPhone using custom designs.
Customization Kits can also be used on tools to change the color or pattern of the design of eight variants, depending on the tool type. It is also a way to replenish the tool's durability, the only exception of tools that cannot be customized are: flimsy Fishing Rods, flimsy Nets, flimsy Shovels, Axes, Vaulting Pole, Ladder, all types of Wands, and Golden Tools.
