It is made of glass that was handmade during the blowing process with a thread. It includes 1.4301 (V2A) stainless steel thread with WOOKAH engraving. The distinctness of theSmoothvase derives from the fact that its cover is completely smooth, clearly transparent, and lacks cuts. As a rare occurrence, the material can include a subtle feature: a thread-like streak within the vase.
It is compatible only with WOOKAH THREAD&GROMMETS model.
Note: It does not match the new edition of WOOKAH with quick-lock system.
