Coffret de 24 crayons aquarelle Winsor & Newton Studio Collection

They are wonderful. They don't break during sharpening; go on evenly and smoothly without blobbing on wet surfaces; colour density is much easier to control; and blending is much easier than with other brands. The colour range has more colours I prefer. I don't do colour portraits, so I can't really judge how well Winsor Newton is suited for that use, but I can say that they are marvelous for landscapes. I can get better coverage in mixed media projects; it can cover very small areas of acrylic paint and work well for adding highlights. I wish W&N had introduced these sets and colours 10 years ago.
I have other brands mainly because of local product availability where I live. These Czech and other British brands seem to use a poorer quality wood which easily splits when sharpening, or after they have gotten wet. The same applies to the leads. The only thing I like about one of the other brands is that a few of their colours are more intense.

Finding these can give either a light or deep, consistent colour if used without water, AND are great as watercolours because you can easily blend.colours together but you have more control than with watercolour paint. The tin they come in is easy to open but also stays closed. The lid lifts right off (no hinge) so then the top layer of pencils can sit in it while you're working. So far none of the pencils points have snapped so I haven't had to sharpen them - huge difference from other brands of regular pencil crayons, Yay! My only peeve is with one colour name. What they call Royal Blue is actually a blue violet and Plum is the red violet. To me that should be called Royal Purple and Royal Blue is R26 G91 B148. but of course people will always argue about colour names! Definitely recommend
