Tesseract

Tesseracts were four-dimensional cubic tools created and used by the Celestials in the idea of matter manipulation, and the ability to teleport anywhere they wished. Every Celestial had at least one tesseract to do their work—creation, but it also had the power of destruction. One such tesseract ended up in the hands of the Asgardian Loki, who then used it as a container for the Space Stone, one of the six Infinity Stones.
However, since Loki was not a Celestial himself, but a god, the Tesseract lost its powers that stemmed from the celestial energy it was made of. Even so, due to its immense power, it was able to safely hold the Space Stone.
