Has anyone seen or gotten their hands on the Fashion Cobra Buckles ........?
Yep, I've played with them. To be honest they leave a bit to be desired. On the plus side they have the wank factor of Cobras, are physically lighter weight (which when you use four or five on a pack make a difference), and are also lighter on the wallet. But on the negative side they feel flimsy and don't have that satisfying "click" when they lock in place. In addition they are a pain to undo/open as the tabs are smaller and with my fat fingers need a bit of finessing. They also aren't cross compatible (ie click a 50mm together with a 25mm) but that isn't the point with this buckle. It purely is aesthetics.
Here is a pack we did late last year with 4x Cobra Fashion:

We don't stock any of the Cobra range, but do do a fair chunk of bags with them. We always get the customer to supply and are happy to work with whatever they choose. Main reason most people chose the Fashion (for us at least) is for the aesthetics and the reduced cost. Just be aware of this when purchasing
