"Overall, the BSUN BCP switch has pretty similar (but not exactly the same) specs as the original BCP. Material-wise, the housing material is still Nylon, and the stem material is POM. One small difference is the BSUN BCP's stem is made of POM S9, a modified POM material created by BSUN to increase the smoothness of the stem. Also, the BSUN BCP has a slightly longer travel when compared to the original BCP." Switches sold in multiple of 10, and will be packed in a zipped bag or in a box.
