Bracelet

Bracelets, Armbands, Wrist Bands, and Bangles are rings or bands that go around the arm.

Castlevania: Circle of the Moon
In Castlevania: Circle of the Moon, these are one of several types of items that can be equipped on one of Nathan's arms. The item called the Miracle Armband is not actually a bracelet, but instead is a Glove, and is called the Miracle Wrist in Japanese.

Castlevania: Harmony of Dissonance
In Castlevania: Harmony of Dissonance, these are considered Goods, rather than Hand Protection, so it is possible to wear more than one of them and also wear a Hand Protection such as a Glove at the same time.
