Thank you for viewing. This is a set of 15 unused PET bottle bodies and 15 Fin Lock caps. The included 28Φmm dedicated lock caps are Fin Lock caps, and the numerous fin-shaped protrusions (fins) attached to the inner circumference of the TE band catch on the protrusions of the bottle mouth when closing. When opening, the band part remains on the bottle mouth, indicating that the bottle has been opened. (Quoted from the internet) Although unused, these items were purchased and stored by an amateur, so please understand that there may be minor scratches or cloudiness that were present from the beginning before purchasing. There are about 50 bottles in stock. #PET bottle #Fin Lock cap #Bottle #2L #2 liters #Square bottle #Empty container #Plastic container #New #Unopened #Unused #Container #Original #Takeout
