All accessories that BikeRunner “sell” is “white-label”, meaning – you can buy whichever (normal looking) lock you want. The cheaper you can buy it, the more money you make on the order. Just like with the tires and tubes. This is also what is communicated to the customer on the website (so they know that the lock isn’t necessarily a certain type for example). As always, if the customer wishes for a specific accessory that exceeds the price of the service itself, ask the customer (before you buy) for more money for this accessory (and ultimately say no thanks to buying it if they don’t approve)

It needs to be the same type of quality as pictured below. Pick a black lock if possible, otherwise any colour will do. It has to be with a chain inside, and cannot be the other ones with just some kind of aluminium/steel threads inside, and it has to be approved by insurance.
