OCALDO Junior Block Set of 6 Watercolors No. 1 Made in England Watercolours READ

This is a set of Ocaldo Junior Block Watercolor/Watercolour paints from my preschool classroom. There are five in the set (the sixth is used up) and one is still sealed in the plastic. The other colors are in used condition. The watercolor paints come in a plastic tray. These colors can stain, so a table covering and a smock should be used when painting.
