The Crucial Tres Leches is the third and final yo-yo produced by Crucial in their milk collection. It is a machined delrin, h-shaped yo-yo, and uses an aluminum spacer system for the bearing seat.
The Tres Leches which was designed by Paul Yath primarily for 3A: "For this style, I like a lot of rim weight, a slimmer shape and a full size. More rim weight means it would be more difficult to do regenerations, but would help to keep the yoyo more stable."
The metal version was discontinued before prodution. Now known as the Delicious with major redesigns.
