I’ve made two sets, one in English and one in Japanese.

• Replaces (almost) any lock, doesn’t block the chain/unchain ability.
• A “random” mode: Pick a random plate everytime.
• Blank plate (which is also fullperm so you can make your own).
• 17 different markings in each language (but they aren’t all the same).

There is also a ‘public’ mode, like on the time release padlocks.
