Set of 4 small blue glass dessert plates with textured edges signed Mexico

This is a lovely set of 4 small blue glass dessert plates with textured edges, made in Mexico. They measure 5.25” inches in diameter. The bottoms say No Broiler No Oven or Stovetop, Mexico. Each is imprinted with a different number as well…27, 25, 16, 7. Unbranded pieces. The color is a translucent blue, lighter than cobalt. Very good pre-owned condition. There is light scuffing from use or shelfwear on the back of one plate.
