Hi Dee!
I figured out that it's actually spelled "Laurentien", and it's a Canadian company - a division of Sanford. Laurentien has a website "Laurentien.com" which has a contact form. If you Google Sanford Canada, ctidirectory.com lists a phone number as 800-668-4575.
Also - THIS IS BETTER, I THINK. I got curious about this, especially when I realized you meant colored pencils (American version!). Since Sanford makes Laurentien, I googled up Sanford single-color pencils and found their Prismacolor line of single colors come in boxes of 12, with eraser or not. Just off the bat found cleansweepsupply.com and went to "colored and drawing pencils" section. You might do better googling around for prices, but my guess is Sanford Prismacolor will be the closest to Laurentien pencil crayons.
Hope this is what you want!
