Samplize produces peel-and-stick paint samples made with genuine manufacturer paint in lines from Sherwin Williams and Benjamin Moore. See samplize.com for details.
Do yourself a favor and just go get small containers of paint if you want to test. Waste of time and money.
Made two orders - 4 days in between. Received shipment confirmation on the second order days after the first, but I received it first. They cite unknown delays in their shipment department for the reason why my my first order was so delayed. But the USPS label was created 7/19 and it took 3 weeks for the package just to be GIVEN to USPS. On top of that the samples are not packaged well. They all stuck to each other and the protective paper they use cannot be peeled on cleanly. Every single one of my samples has tons of paper residue on it.
