Store your things with an extra dimensional flare with a tesseract.

I am not liable for any loss of material possessions to the fourth dimension through the use of the Tesseract Container. You agree that any losses that may occur is a skill issue and no negative rating will be given.
This item may phase out of our plane of 3-dimensional space during printing and thus fail printing, in this case stop printing immediately and build a four dimensional containment cell to contain this anomaly at once.

Failure to properly contain the item may result in unforeseen injuries and in the worst case, phasing into the fourth dimension permanently.
