A method of improving a fishing lure by taking an existing fishing lure and adding a powdered metal such as lead or tungsten to the soft material during the re-production phase to add weight, wherein the amount of added weight enables the resulting improved fishing lure to sink to different depths at a faster sinking rate. The subject disclosure contemplates first-time production of fishing lures with added powdered weight as well as re-production, wherein a pre-existing lure of substantially only soft material is melted down, powdered weight is added to the more viscous, melted soft material, which is then allowed to reconstitute through cooling, thereby resulting in a heavier version of the pre-existing lure.

To provide a resin composition for three-dimensional shaping. The resin composition includes a polyfunctional urethane (meth)acrylate having a molecular weight of 700 or greater and 1,300 or less.
