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

The lid is a little tougher to get on but for the cost they are great. The lid does seem to go on easier with their cups rather than a 3m cup.

Good product but there are some things that could get some attention.

MPS sells a fantastic kit. This review is for the 6oz set. I included some pics with 3 different size cups to have as a reference Again, this is for the 6oz cup. Super happy with all that was included for the price. Zero leaks or drips! This may help some users having issues with leaking. When installing the screw on lid, think of it like putting a lid on a container. Push down slowly all around the circumference until it is bottomed out. You will know you have it right when the screw on collar falls into place and tightens right up. Cross threading of the collar is a hint that the lid may not be fully seated. Works for me, hope this helps some having problems!

I have a Black Widow gun and I have tried everywhere to get an adapter to fit these. I almost bought an adapter from China but supplier said it wouldnt fit my gun. If anyone knows where to get one let me know.

These are ok you have to make sure they snap evenly for them not to leak took me a few times of it leaking to figure out why it leaking it has a ring that the top and cup have to link together like a ziplock to create a seal. Once sealed and material is used you cant refill it by openinit back up it just creates a mess might as well just make another set up. Id say great for very small touch up jobs where u use 3-4 oz of material at a time with one single use. Not the greatest but does work.
