These cute bar shaped little flip locks sit on the edge the finished edge of the front flap of any bag.  They are so pretty and very easy to install! These little cuties are not very deep inside and can really handle a front flap that is about 1/8" (3mm) thick or one that can be compressed to be that thick (foam). I recommend a strong layer of bag stabilizer, such as Peltex, Timtex, or Fast2Fuse inside your front flap for strength. Measurements: Width 2 3/8" (6 cm) x Height 3/8" (1 cm)
