To be honest this is an ok palette cup, but it’s not as described.It’s in the title, they say it is a double cup, that it is stainless steel and that it is with lid. Only one third of this all it is true, the cup is made of stainless steel. They should really revise the listing.So the cup is very small and it is relatively well made, but it does not have a tighter lip or anything to prevent any spill.It also does not have a lid, so the medium will continue to evaporate when not in use. This is a big problem. I would never throw away linseed oil, or liquin or any other medium that I use, and I would also be unable to put it back in the original bottle once it’s been used due to contamination. So using this little palette means that whatever I did not use in one painting session will have to go in the trash. I cannot afford to be so wasteful.So yes, make sure that you understand what you’re buying: it is small stainless reel cup with a clip , it will attach to a flat palette only, not to any other type, not to recessed ones, not to butcher’s trays. It will also stay open and let your medium evaporate.I am slightly disappointed , I have to admit, I think that $10+ for this tiny cup is quite a high price.While it is well made, the cup is not as described* Near a water bottle /cap for size reference *Thank you
