Set of 2 Seashell Shaped Melamine Plates Yellow White Coastal Beach Tableware

I have a matching set of 2 melamine seashell-shaped plates in white with bright yellow rims. Each measures approximately 8 across and has a dimensional shell design with raised radiating lines and scalloped edges. The undersides are marked Made in China, Not Microwave Safe, and Dishwasher Safe Top Shelf. A fun set for coastal, beach house, nautical, or summer table settings.  I like the bright yellow-and-white combination, molded seashell shape, glossy finish, scalloped edges, and lightweight melamine construction. These are dishwasher safe on the top shelf but are not microwave safe. The set includes both matching plates shown.  I found these in good pre-owned condition while handling and photographing them. I see light surface wear and scattered marks consistent with previous use, but I did not find any cracks or breaks. Please review my photos for your own assessment of the cosmetic condition.
