There are three ways players can get in-game graffiti:
Players have a chance to receive graffiti as a free weekly drop for ranking up.
Graffiti Boxes featuring art created by Steam Community Artists can be purchased. A portion of the proceeds from sales of Community Graffiti Boxes is shared among the community artists.
Individual graffiti patterns can be purchased from the Steam Market.
There are two different types of graffiti patterns; monochrome and multi-colored. Monochrome (one color) patterns are received as rank up drops and multi-colored patterns are received when purchasing a graffiti box. Both types of graffiti can be traded and sold on the Steam Market.
When a player unseals graffiti they can apply that pattern 50 times. Players who unseal a graffiti pattern they already have in their Inventory will receive 50 additional charges to their existing supply.
Players can apply graffiti once per round, or every 45 seconds, whichever is shorter. Getting a kill in a round-based game mode will allow the player to apply more graffiti.
One application of graffiti lasts 7 minutes and degrades over time until it is no longer visible.
The graffiti preview shows where and how the graffiti pattern will be applied. If there is no preview then the surface does not support graffiti.
Players can have as many different graffiti patterns equipped as they want and can use the in-game graffiti menu to select and apply a different graffiti pattern at every application.
All graffiti patterns can be viewed in players' inventories and in the in-game graffiti menu.
Graffiti can be sold on the Steam Market and traded as long as it is sealed. Once a player has unsealed their graffiti it can not be traded or sold on the Steam Market.
Yes, but the graffiti must be unsealed. Once you have unsealed the graffiti, locate the item in your CS:GO inventory, right click on it, then select 'Delete Item'.
