Berol Mirado FLASK MARKER for Glass Carboy and Erlenmeyer Flasks – Red Peel Away China Marker

Peel-away wax pencil for writing yeast information on Erlenmyer flasks and other glassware. Works great on glass carboys and wine bottles to record what in in them.  Just write it on there!  Stays readable until wiped away.  I used to use paper notes or sticky notes but they kept falling off or getting lost.  Now I use these and always have one around.  These red markers write smoothly and legibly on both porous and nonporous materials such as porcelain, glass, metal and plastic. Pull the string and peel down strip to refresh the tip of these erasable markers.
