Review on FMS Ravenox 3/8-Inch Contoured Buckle: High-Quality Paracord Bracelet Buckles for Reliable Replacement Hardware in Backpacks, Tactical Gear, and Webbing by Carla Anderson

Just received and thought a comparison picture would help. I ordered four buckles from FMS and a GooDeal lighter with whistling stone. The comparison bracelet consists of a large Hobby Lobby buckle for an adult male. The gray whistle is her 3/4 and the yellow whistle is 5/8. As you can see the difference in size is small, the gray is a bit wider. It seems to me that whistles are only suitable for grown men, and the other two for babies. I like that they are made in the USA and I like their quality. I just want them to do the sizes in between.
