I can't recall the policy on sales links so I'll try to stay on the safe side.
Sell Geek has "Re Imagined Retro Tuck Buckle" that at least one buyer reports are nicer/better constructed than the buckles that come on the Anovos BSG jackets. These are the Warrior Jacket buckles under a different name.
In addition to possibly replacing your stock buckles its something to be aware of if anyone is looking for loose buckles for replacement on other costuming or a new build.
To Me the buckles on the Anovos Jackets are just like the Buckles That Hawk Worley is Selling for $30 a set on Ebay
