Do NOT use an Epoxy resin that is used to coat tumblers and tabletops with this mold. It is made to use with a Casting Resin such as easy cast or Alumalite amazing resins. This mold is a 2 cavity Plastic Straw topper Mold This makes a cute almost 2" wide Straw topper that fits perfectly on a coffee shop straw- Pieces will pop out easily I used UV resin to make the topper shown. UV resin and pigments- Glue part A to Part B This is an original idea by Molded From love All rights are reserved
