NextGen Reefs ceramic frag mounts are perfect for hobbyists looking for a strong, clean base to attach coral fragments to for growout or resale. Fired at nearly 2000 degrees in a high-temperature kiln, they're completely inert and safe. Unlike many imported frag plugs on Amazon, ours are made in the USA with our exclusive “Soft Ceramic,” which is strong but at the same time soft enough allowing the stems or "posts" to be easily snapped off if desired often by just using your hands! They also feature a brushed, textured surface to maximize glue adhesion, never need curing, and are shipped dry—just give them a quick rinse, and they're ready to use.
