Very strong contrast between pencil & print colors is recommended eg. black print on yellow pencils.
Diacritics are only available with the 10pt Spanish Helvetica typeface font.

Pencils are grouped below by manufacturer. No manufacturer makes all pencil colors.

Differences between manufacturers' pencils include:

• Pane widths - Dixon and Group 1 pencils use only use 8pt typeface fonts because they are narrower. Group 2 uses most 10pt and all 8pt typeface fonts. Group 3 uses all 10pt fonts.
• Ferrule & Eraser colors
• Group 1 and most of Group 3 pencils are USA Made, the others are hybrids of USA & China.
• The differences are readily apparent so mixing and matching pencils from different groups within one dozen cannot be ordered. Explicitly Yours does not recommend mixing different manufacturer's pencils within a dozen, but if you really need to, then order multiple dozens and mix them at the office, home or school.
