Custom Shop Paint Mixing Cups Plastic Measuring Cup Epoxy Resin, Disposable or Reusable, 10-Ounce (Half Pint) - Box of 100 - Graduated, Mixing Ratios, Automotive Painting Acrylic Art Crafts Kitchen

these are just what i wanted. the important thing for me was very clearly marking the kind of plastic - polypropolene....which can handle resins that willl melt a typical "plastic' picnic cup. the picnic plastic (aka solo or 'big red cup') can handle most two part alcohol based epoxy's but not resin systems where acetone and related chemistry is used. just finished my two part clear coat project, no melted cups :) and have plenty left for my next project.

Good quality with exceptional markings for paint mixing

Works great

These are well designed and very durable. I'd give them a 5 star except the dimple in the bottom keep them from sitting flat. If my work required a touch more precision I would use them.

Perfect size cups for my home shop needs. Should contain more than 12 lids.

Ratios are way off.

So far so good as far as mixing cups go. I wish they had more lids. These cuts last me forever as I try to clean them as often as I can.

I do epoxy resin crafts and I have made the mistake in the past of eye-ing my part A to B ratios which lead to sticky surfaces and gummy casts. These cups are clearly marked in ounces so I can mix by volume parts, which works well for my purposes - and it is nice that they are also disposable, so I don't have to chip the dried epoxy out to use again.
