Master Paint System MPS, 4 Pack Set of Large Size 27 Ounce (800ml) Hard Cups and Retainer Rings - 4 Hard Cups and 4 Rings for Use with The MPS Disposable Paint Spray Gun Cup Liners and Lid System

These work great. Quality is high

Great quality and fast shipping. Perfect starter kit.

Economical, the liners fit perfectly in the cup and the cup collar threads easily on the cup, will buy again.

I love these cups! Some reviews mention leaks, I have had none but probably because I am very careful assembling the cups. The liners are cool, they drop into the hard cup. Pour the paint in, then put on the top(with the feed hole and integrated filter). This is tricky, it has a number of clicks as it settles into the liner. It has to be settled all the way in, kind of subtle, I suspect if this is not done then leaks will be had. Next is to screw on the black retaining ring. This too is fiddly, very easy to cross thread. I sight from the side and watch it go on. Also when screwing it on it can be screwed on too tight and skip threads, it needs to be 'just tight enough'.There are no directions and very few if any online tutorials so I will continue. Once filled and capped keep the cup with the orifice pointing up and push the gun onto the cup. This has a few hitches/bumps as it goes on. Once it is completely seated twist one notch for complete seal. Then attach the gun to air and pull trigger with the gun upside down and all the air will be sucked out of the cup, leaving only paint in the now collapsed liner. Very cool! This is what lets you paint upside down without sputtering, paint keeps flowing.I tried to refill a cup and it didn't go well. If I need more paint I use a new cup. If I have lots left over I put the cup on top of my paint can and let the un-used paint dribble back into the can.Overall way better than the stock metal reuse-able paint cup, I will never go back!

came here after using dekups for years, and im not gonna lie, my first few tries I hated them, but.. once you kinda figure them out, they're actually not bad, these are pretty much single use, (in my case) when I tried to refill and reuse, in the same paint session of course, the cup would no longer get a solid seal with the cap and it would leak, getting them off was weird at first, but you just flip the gun ,pull the trigger to let the paint flow back into the cup, twist it until the hooks are on the slimmest part of the adapter and ever so gingerly wiggle it off , Ill use them again, except Ill get the next size up to avoid cup swaps during a single session, give the iwata a few solid shakes to make sure everything is tight and you'll be good to go

Extra hard cups are always handy and save time. You can have 2 ready at once, etc etc. Also nice to not have to stop and clean up until the end of the day.

Great product perfect for painting
