(↑ Back to the ItemDex index.)
(hex:73) is a glitch item in Pokémon Red and Blue.
Its name is taken from mojibake of Pokémon Red/Green's untranslated "マスター" (Master) string. "マスター" (Master) is also the hex:73 glitch item in Japanese versions.
Using it both in and outside of battle causes a glitch text box to appear that possibly cannot be exited.
