Description:
SCP-4707 is a 1m x 1m x 1m cardboard box. It appears to be held together by tape but appearance but said tape is instead part of SCP-4707 itself. In addition there are no other markings on SCP-4707 apart from several large symbols, presumed to be an unknown language, printed in one side. Only one side allows to be opened but only manually as trying to open it any other way or if 2 or more individuals try opening it as once will lead to SCP-4707 sealing itself for 1 hour.
Although SCP-4707 appears to be made of cardboard it is made of an unknown material.
SCP-4707 gives of next to no information including having no measurable mass, no radiation emission and basically does not exist. But only when determined by machines and tools as an individual will be able to perceive SCP-4707 just fine. When and individual holds SCP-4707 they say it weighs about the same as a litre of water, as such the foundation deems SCP-4707 to have a mass of around 1kg.
When SCP-4707 is opened by an individual SCP-4707 will then contain whatever the individual needs most. This can be anything from a physical object like a glass of water to a conception like happiness. Although when it comes to anything physical the only restriction is to what can fit into the 1m x 1m x 1m area.
Note that SCP-4707 will not contain what an individual wants or thinks they need most but rather what they actually need or what SCP-4707 perceives them to need. As such it is believed the space inside of SCP-4707 is infinite.
The origins of SCP-4707 are unknown and was only discovered when it was left at the entrance of Site ██████. Security cameras show no new information as all sensory equipment went dark for 0.1 seconds, in this time SCP-4707 appeared in front of the entrance leaving no signs as to how it got there.
