High Density Weights are support items developed and created by Mei Hatsume, who won a competition for the best design.[1]
Description#
The weights are ultra-compacted to make them easy to wear around someone's arms or legs. They were used by the U.A. teachers to reduce their speed and drain their stamina to give the students an advantage during the First Term Final Exam.[1] Each weight adds about half of the wearer's body weight.
