Model Expo - 5mm Boxwood Bullseye 24 pcs

Model Shipways Bullseye, Boxwood 3/16" 5mm 24 pack

These round, grooved blocks function like a deadeye except there is only one hole through the center. They are also used as fairleads. You can make a Bullseye from a deadeye by reaming out the 3 center holes into a single hole.
