SCP-198 has taken numerous forms since coming into Foundation possession in 19██. Since acquisition, SCP-198 has been observed to have had dozens of different forms including a Styrofoam cup, █████████ brand glass beer bottle, ██████ and ████-████ brand aluminum soda cans, an oversized shotglass that read “One Tequila, Two Tequila, Three Tequila, Floor”, a plastic water bottle with a █████ label partially peeled off, and [DATA EXPUNGED]. These forms always appear partially filled with the expected liquid a vessel of that type would contain.
Currently, SCP-198 appears as an ordinary white, porcelain coffee mug with blue, vertical stripes evenly spaced around its exterior. There are no visible manufacturer markings or otherwise remarkable details about its appearance in its current form. The object has resisted all attempts at destruction or sampling for further analysis. When inactive, SCP-198 can hold the expected 240 mL (8 fl oz) of liquid that any standard coffee mug would hold.
