Siebold Primrose Supply Cases

"Of course, that's ignoring the real rewards! All you need to do to grow your Seed is to keep playing Combat Arms. Play for 60 minutes and your seed will grow into a Siebold Primrose Sprout, which can be harvested for a Siebold Primrose Sprout Case, which contains a powerful, random Function item, including the Infected Mutagens, Super Elite Moderator or a Weapon Renewal Kit!"

The Siebold Supply Cases, first released on the 10/25/12, were rewards from the Lead Farmer Event.
