I am selling a set of two "rock exotica Omni-Block 1.1 swivel pulley single sheaves" that I directly imported from a US arborist supply distributor about four years ago. I used them once after purchase and have since stored them indoors. Since I will not be using them in the future, I would like to sell them as a set to anyone interested. The purchase price was $95, excluding shipping and customs duties.
