Rivet Seal

Product name: Rivet seal
Helps protect barrel lid flanges from rust
These lids are made of painted tin foils.
The Rivet seal foils are galvanized and stainless steel.
Has two safety cutting lines in the middle of the lid.
In case of an attempt to open the Rivet seal, the foil is torn from the center, the seal is discarded and there is no way to re-seal it. This advantage makes it impossible to cheat and manipulate the seal.
The interior of the Rivet seal surroundings is filled with white polymeric material. This advantage makes the lid stay in place tightly and there’s no space left in the surroundings of the lid to manipulate it.
