The best advice I ever received was to buy the best artist materials that you can afford. In my mind, Winsor & Newton provides the best products that money can buy and if you buy the best, you will never be disappointed.
I bought the field box in 1982, as I was building up my supply of watercolors for the future, and I still have the field box and use it today. It was my first experience with using watercolor pans which completely eliminates the hassle of watercolor tubes. The problems with tubes includes the paint drying inside the cap, and freezing to the tube making it difficult to get off, and eventually the paint in the tubes dries up solid.
A tip for getting frozen caps off the tube is to heat the cap up with a match or lighter. Be careful though because the caps are made of plastic, and will easily melt. If the paint dries up, you can still use it if you cut the tube open and peel off the metal. Re-wet the solid paint the same as if you were using a pan of watercolor.
The Winsor and Newton Field Box is made of plastic, is durable, and closes up into a small compact package that you can take with you anywhere. It also has a small water bottle, and small watercolor brush as well.
