Wanted: pair of bikebins or suggestions

I am looking for a pair of (ideally black) bikebins (https://www.bikebins.com/). Unfortunately, however, it seems as though the designer is taking a break from the business. They seem a fanastic product, and are exactly what I am after.

Does anyone have any tips to where they might still be stock? Have a pair which they would be willing to sell? Or know of a similar alternative (a rigid, lockable, weatherproof pannier)?

Any suggestions or offers greatly appreciated!
