Machined 13g pure tungsten framework weight. The loads are smaller set alongside the metal loads since they are easier to install with a cleaner design. The super small loads cause reduced CG comparing to standard loads. Made from actually uncommon and hefty pure tungsten product, not an ordinary tungsten combination. The pure tungsten gets the best density framework and it's also the heaviest metal material allowing to produce tiniest size weights comparing to almost any other materials. Fast & effortless accessory to framework. Marked with fat value for simple recognition.
