Master Paint System MPS Disposable Paint Spray Gun Cup Liners and Lid System, 50 Pack Mini Size 6 Ounce (180ml) Kit - 50 Cup Liners, 50 Lids with Strainer, 1 Hard Cup with Retainer Ring and 20 Plugs

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 didnt 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!

Good sizes for a good price.

Worked with my 3m pps cup adapter already on my gun, cheap cups compared to the name brand 3m ones but work great will buy again

Works great

They say they work with all PPS adapters. This is not true they do not work with PPS 2.0.

Works like it should. Ive had no big failures or loss any significant amount of paint. Works well and seals good. No compliants.

So glad I got this for my HVLP set up. Makes cleaning up much easier. The built in filter in the cap means skipping the pour over filter into the spray cup. Overall you can spend more time painting and less time prepping and cleaning.

I was not happy with the durability of the product. I guess you get what you pay for.

Great packaging! Easy self explanatory operation. Great product for clean environments.

I like the system and trying to adjust to it.
