I sell Prismacolor Premier, Verithin and Karimsa pencils. Below is useful information about them.

Prismacolor Premier pencils are soft, wax based pencils from the USA. Made by Berol Sanford. They come in a range of 132 wonderful colours as well as some discontinued colours which are hard to find but not yet impossible. Prismacolor Premier pencils blend well with each other allowing the artist to create an endless range of hues. They will draw on many surfaces including wood, vellum and metal. A colourless blender is also available, this is made of the same wax base material as the coloured pencils and is used for burnishing, blending and softening hard edges. They also blend out well with spirit blenders like Sansodor this is useful for underpainting your work and is great for card crafters, as a professional finish can be easily achieved on your stamped images. This is known as 'The Magic Pencil Technique' Prismacolor Premier pencils are not watersoluble.

Prismacolor Watercolor Pencils come in a range of 36 colours, unlike the Prismacolor Premier pencils these are water soluble. They easily blend with each other to make more colours and tones. All the colours in the Watercolour range match their namesakes in the Premier range so work well together on a mixed media piece.
 
Verithin pencils come in range of 36 colours which match the premier pencils. They have a hard thin lead and are used for fine detail, lettering and neatening edges, they are also great for marking fabric for quilting and dress making.
 
Karisma or Karismacolor pencils are now discontinued, they were made by Berol Sanford in the UK until 2005. They are the same as Prismacolor Premier pencils and even have the same colour codes but they have a natural wood finish and a slant at the end, much more stylish in my opinion. They came in a range of  108 colours but it is closer to 120 colours when you count some of the early colours which where discontinued before the entire brand was. These pencils are very hard to source. Karisma also come in a range of watercolour pencils, also discontinued.
