Mystik™ tubes have been created with unique shaped inner barrier multilayer membrane covering tube shoulder, neck and orifice. With yet another innovative closure with integrated wedge (patent applied) helps consumer to pierce the tube orifice membrane just before use. Post use, the piercing wedge can be concealed within the closure, to avoid contamination due to pre and post piercing action. Essel’s patented multilayer laminated tube body keeps the squeezed area collapsed together and restricts air suck back.
