They combine all grades: they are pleasant to handle for children, they have very nice bright colors, they glide great on plain paper without having to press hard to mark, they blur easily, they do not break even a series of falls, and the hard case is opened by bending behind to serve pencil display: small hand them spontaneously for them because it's more fun and we immediately see if any are missing. Closure system may be a little rough for very small hands, even my three year old son is doing well! 3rd bought box, I changed school pencils, very poor quality, hard and brittle, by them in the kit my son who rejoices every day.
