Review on Stylish Custom Dog Collar With Fade-Proof Printing And Rustproof Buckle - Made In The USA by Christine Zuniga

HIGHEST QUALITY BUCKLE: We use Duraflex acetal buckles rather than more common nylon or metal buckles. Acetal buckles have higher tensile strength than nylon and perform better under freezing or arid conditions. We chose acetal over metal because metal corrodes in salt water, creating problems when dogs go swimming (as they often do here in the Pacific Northwest). Duraflex buckles are considered among the best buckles in the world & are used by the US military.
