    flex-it 40

    Flex-it 40 is easy to use, mix and work time allows me( a novices caster ) to de-gas and pour without the stress of a faster product. I've been using it to make soft handles for hand tools. Love Flex-it products.

    Great for Keshi style pieces

    This stuff is just great. It produces a consistent result that you can rely on. Takes pigment and strontium aluminate powders really well. I wish it cured a bit faster, but you can’t argue with the results!
