The pumps shown are calibrated so that one pump from each, the resin and the hardener, gives you exactly the right proportion. No more measuring cups or guesswork. And with this setup, it's super convenient to mix a batch of epoxy whenever you need it. The cost of a quart of resin, a pint of hardener and the pumps is a little steep, but the epoxy will last for years, and a fresh batch of epoxy is just a few pumps away. Make sure to buy pumps that are calibrated for the epoxy you're using.
