What is the difference between the plain window and duo window overlays? Does it actually make a difference to the user?

Good afternoon, Thank you for your enquiry. The Duo ruler has an opaque strip approximately one centimetre from the top, this means you can highlight one line of text and block out the next few rows, this is particularly useful if the user is easily distracted by what is next! The plain window ruler has a fine tracking line again approx 1cm from the top but the rest of the ruler can be seen through. Kind regards Crossbow Sales Team

I knew about a yellow rulers for dyslexia ..what are the other colours for x

Learners with dyslexia and other spld's can respond individually to different colours. I allow my learners to try out the different colours and choose which one they feel most comfortable with when reading. Often it is varying shades of yellow or green but blue is also an aid to some who are light sensitive.

Does this assorted pack include one of each colour?

The pack I received was exactly as the pic. 3 yellows and 2 greens etc.

Hi i was wondering how i can go about ordering just light grey overlays 10 pack please.

No idea, have you tried contacting the company?
