A hand-made flash drive with an engine turned on by turning the valve rotates the illuminated clover corated with the symbol of four-leaf clover, which is believed to be able to bring good luck, made in the style of "steampunk", made of brass. Can be equipped with a memory of another size, if desired. Covered with patina and polished. Status excellent gift for someone who appreciates the style of steampunk.
