1-3/4″ aluminum cube $50. This is a one time sale. These are over runs from the Kickstarter Project. The large hole on each side is 1.5″ which was made for the BilletSPIN Pro. I have 20 of these and once they are gone they are gone. Shipping will be $5 domestic and $10 international. I will ship these Monday of next week. Please respond here if you want one or two or twenty so everyone else knows how many are left. Thanks!
