Series 25 Ball Bearing BlockThe Series 25 Ball Bearing Orbit Block is a 1in (25mm) single sheave ball bearing block with becket and lashing head designed to give you high strength and low weight for dinghy and small boat control lines. Its primary benefit is reduced friction under load thanks to a two stage ball bearing system built for control line tasks. Problem: high friction and heavy hardware slow sail handling on small boats. Solution: this block uses a high compression

I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
