4D Pocket

The 4D Pocket is one of Doraemon's and Dorami's default gadget. The inside of pocket is 4D, functioning similarly like a small portal(in other terms, a 'wormhole) that allows any item to be inserted inside it without using much space. The inside of the 4D Pocket looks like a limitless, floorless room. The 4D pocket is literally the most used gadgets in the entire series. The Pocket cannot be broken, unless cut into pieces, which the items inside it may either be destroyed instantaneously or immediately spewed out. Both Doraemon and Dorami wears the 4D Pocket on their abdomen.

Function

Doraemon and Dorami uses their 4D pocket to store any item or relatively carriable by their strength. The 4D Pocket allows things to enters its small opening, because it may 'deform' them so they may fit(through the opening). For example, the Dokodemo Door is virtually impossible to be inserted into it, but when Doraemon and Dorami put it or withdraw it, the Door seems to deform in shape for while, then revert to its original form.

Since the inside of the 4D Pocket is of another dimension(namely the 4th dimension), carrying the 4D Pocket around is like carrying an empty pocket, almost weightless.
