My latest order from the Ardennes Belgian came with a nice surprise, with the Belgian stones all newly packaged.
These attractive boxes have a top cover/lid that slides off (which is more secure than the usual lift on/off), and also have a nice padded bed for the stones to recede into. This provides not only a safe package for shipping around the world, but also for storing at home once your sharpening has been concluded.
Here are some photos of the new packages. Please note, some of the small stones still may come as they are (without these storage boxes).
