Our plastic buckles are made of high quality polyoxymethylene(POM) and they can be a key component in any project webbing based of the size. The strength of this kind material is durable enough for long time use. User-Friendly-design is the other strength for the side quick release buckles which are the best choice of webbing buckles for easy one handed release and avoids accidental release. Good replacement for backpack, luggage, paracord belts and other products.
