Wacky Tube Wacker Bud Press - Stainless Steel The Brand New Wacky Tube Wacker Press will create a uniform tube of buds and flower that will press evenly, ensuring a maximum rosin yield in every press. Wacky Willy's rosin bud press will squeeze buds or shake into compact cylindrical pucks or logs that will easily fit into mesh rosin tube bags ready for pressing. The tubes output will create a 1.34 inch wide and 1 to 5.9 inch long (max) bud log. This uniform shape and even height will generate a higher yield during the rosin press process.
