White ribbed screw cap, self-sealing DIN 18 ring for bottle.
The "self-jointing" side, which does not require a joint, allows multiple uses because there there is no possible reaction with the product contained.
 
In addition, thanks to its DIN18 ring, the capsule,  in Polypropylene, is inviolable. This certifies that the bottle was not opened between the time it was packaged and the time the user will open it. _cc781905-5cde -3194-bb3b-136bad5cf58d_
