Slightly shorter than 3M 18-22 AWG connectors (0.59" (15mm) vs. 0.625") and slightly heavier (0.028 oz. vs. 0.026 oz.) . As announced, the number of packages was 100 pieces. I bought 16-14 AWG connectors from Crimp Supply and only got 98 out of 100 twice. The material of the part is advertised as T2 (China, UK) copper, which is equivalent to C11000 (US, ASTM). Overall this appears to be a quality butt connector if you don't mind that it's made in China.
