Brokkr and Eitri the dwarves that created three precious objects for the Gods. In a bet with, the trickster Loki, he bet that the dwarf brothers Brokkr and Eitri, that they could not make anything as fine as the gifts, as another group of dwarfs had already made for the Gods, which was a golden headpiece, a ship, and a spear. Eitri and his brother Brokkr, then crafted Gullinbursti “Golden Bristles” which is a living boar with golden hair, that shines so bright that it turns night into day wherever it travels, Gullinbursti can also run better than any horse through water or air.
The two brothers also crafted Draupnir “the dripper” it later became Odin’s magical gold ring, it has the ability to multiply itself: Every ninth night, eight new rings will ‘drip’ from Draupnir, each one of the rings have the same size and weight as the original ring.
The third object the two brothers made was Mjölnir, it would become Thor’s mighty and magical hammer. All these objects were made in the bet with the trickster Loki, which he ended up losing to the two dwarves.
