This is a magnet made by embedding a 13mm diameter super-strong magnet into a black ebony round rod and hammering a 10mm diameter black ebony round rod onto the top. The surface polarities are S pole and N pole, so they attract each other with a strong force. Of course, it will also adhere to iron parts, so it can be used as a high-quality ebony magnetic holder. The surface is protected with linseed oil. The approximate size of the round rod is 28mm in diameter, 29mm in height, and the total weight is 51g. [Notes] This item was made by polishing a black ebony round rod, and there may be small scratches that occurred during manufacturing, but the expression "no noticeable scratches or stains" is used. Due to being handmade, there may be fine scratches, chips, saw marks, imbalances in left and right or 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.
