Company History
In the early days of container shipping, all containers were closed and secured by ordinary padlocks with keys. But the key for a padlock on a container presented a problem as the keys were often delayed or lost at final destination.

This caused Michael Remark to invent a locking device that had to be cheaper than a padlock but with the same security.

In other words: " A padlock intended to be opened by a bolt-cutter".

With his first design, Michael Remark founded in 1974 OneSeal ApS. On May 1st 2015, OneSeal celebrated its 40th anniversary.
