SBYURE Plastic Graduated Measuring Stirring Review

These mugs have ribs on the inside that prevent the material from mixing efficiently and prevent the material from spilling onto the sides. Then the same protrusions prevent the resin from being squeezed out of them. If you don't use them for resin, they're not bad. You get a lot of these and the ml markings are different on both sides so you have a lot of measurements overall.

I mainly use airbrush mixing cups and wanted something small with measuring lines. The biggest problem with cups are the 4 "ribs" inside the cups. You can't stir paint properly without splattering paint all over the place. When stirring, the stick gets caught on the fin and shakes the paint out of the cup. The money saved on these "cheap" mugs is spent on paint.

If you are buying them for what they are intended for (medicine, measuring liquid) then they are perfect. If you bought them to make resin or other things you need to scrape off liquid, they are not recommended. There are 4 notches inside the mug that make scraping items harder than necessary. It is desirable that the inside of the cup is smooth around the entire perimeter. I bought them for the price but will not buy them again for my purposes.
