It takes its name from the unused Japanese string "かいがらバッヂ" (ShellBadge), which is also the hex:63 glitch item in Japanese versions. The string was untranslated, resulting in the string "ws# #m#" as mojibake.
Using this glitch item both in and outside of battle prints the text "The POKéMON BOX is full! Can't use that item!" even if the current storage box isn't full.
