This is a No Hassle Container for the Z-butt artisan creation platform. You would use this to make 2 piece molds of your sculpt or blank. (note: Sculpting base or Stem Cavity is not included, it is shown for reference)
The No Hassle Extender allows you to extend your No Hassle to accomadate larger sized ZBut's. (max with 1x Nohassle and 1x NoHassle Extender is 2.75u Zbutt) for Larger, I recommend Lego's.
