Nether Warper

This would be a really rare item found only in the loot of Ruined Portals.

This item, if used, will instantly teleport the player in the Nether, but it won't link to any Nether portal; instead, it will calculate the coordinates and teleport the player there. When the player is telephoned, it will let behind some purple particles.

However, the item will break after the use.

The Warper can also be used to teleport the player from the Nether to the Overworld.

This item doesn't function in the End.
