Sprue/ Runner Holder for building Gunpla, 30MM, 30MS, or other plastic model kits. I included the 6 slot version and 1 slot versions. These require no supports and you do not need to apply much force when adding or removing your runners. Have built a few kits using this holder to test it's durability and it is holding up very well.
