There are several recommended stores and online platforms where you can find paint-by-number and diamond kits designed for adults. Well-known brands and stores such as “Diamond Art Club”, “Paint Plot”, “Craft-Ease” and “AliExpress” offer a wide selection of kits with varied and high-quality images, this is where I bought mine. These shops provide a complete set of materials, including canvases, brushes, paints, or diamonds, needed to complete a project. Alternatively, you can also search for kits at art stores in your area or on specialized websites that offer a large selection of kits in a variety of brands and styles to suit your creative needs.
