Item #: SCP-505

Object Class: Keter

Special Containment Procedures: SCP-505 is contained in a 50 m x 40 m x 10 m room at Site-██. SCP-505's containment area is to be sealed other than one secure airlock and a series of pipes allowing transport of SCP-505-1 to storage tanks in the event of SCP-505-1 reaching levels in which it poses a danger to containment. Sprayers for 4 M NaOH are to be available through SCP-505's containment area and the rest of Site-██ to combat a containment breach. In the event of a spill of SCP-505-1, the affected area should immediately be covered with an absorbent material (commercial blotting paper is currently standard for this purpose) and doused with alcohol or acetone if NaOH is not immediately available. NaOH immersion is the method of choice for SCP-505-1 containment, followed by incineration of affected material if practicable.

There are currently ██ instances of SCP-505-1 points of secondary contamination outside SCP-505's primary containment area. Containment in these areas is variable but efforts have been made to make procedures as similar to those of the primary site if possible. Of these secondary contamination zones, █ are unable to be fully contained at this time resulting in the spread of SCP-505-1 throughout the environment. These sites are to be monitored at all times and countermeasure development is of the highest priority. For a complete list of SCP-505-1 secondary containment sites, see Document 505-14A-███.

Description: SCP-505 is a Model ████ Faber-Castell fountain pen, produced in 2001. For documentation of its acquisition by the Foundation, see Addendum 505-2. It is identical in all respects to a standard fountain pen apart from its association with SCP-505-1. SCP-505-1 is the black ink produced by SCP-505, which exhibits the property of self-replication. SCP-505-1 spreads at a variable rate, affected by the substance it comes into contact with and the amount of SCP-505-1 present. Quantities of SCP-505-1 have been shown to increase at rates between 0.5 and 540 mL per second. Standard ink-removing chemicals are able to partially remove SCP-505-1 and inhibit its spread; however, sodium hydroxide is necessary to remove SCP-505-1 contamination completely, and has shown to be ineffective in environments with particularly high SCP-505-1 concentrations. Fortunately, the growth rate of SCP-505-1 appears to be inversely proportional to its quantity at high concentrations. Whilst the observed effects of this are negligible in most cases, this inverse growth phenomenon provides the only explanation for the partial containment of SCP-505-1 despite a number of cases of large-scale environmental contamination which were projected to otherwise lead to an NK-class end-of-the-world scenario.

SCP-505, The Ink Stain

An ink pen capable of producing liters upon liters of ink—you won't find it naturally in the game; it’s creative-mode only. Be careful, though: once you start using it, there’s no way to stop the flow. You could try using sponges, but they won’t be of much help,

 P.S. You can use ink or lava; it will remove the ink from the surrounding area.
