This is a magnet made from a round ebony rod with a 13mm diameter super-strong magnet embedded inside, and a 10mm diameter ebony rod hammered into the top. The surface polarities are S and N, so they attract each other with a strong force. Of course, it will also adhere to iron, so it can be used as a high-quality ebony magnetic holder. The surface is protected with linseed oil. Approximate dimensions of the round rod are: 27mm diameter, 29mm height, and the total weight is 51g. [Notes] This item is made by polishing a round ebony rod, and there may be small scratches that occurred during manufacturing, but the description uses the phrase "no noticeable scratches or stains." Due to being handmade, there may be minor scratches, chips, saw marks, imbalances in symmetry, and deviations in the central axis due to processing. Please refrain from purchasing if you are concerned about such details. Linseed oil may stain clothing until it dries, so please be careful. Shipping will be via Yu-Yu Mercari Mail Yu-Packet Post, an anonymous delivery service.
