A Trusted Friend in Every Classroom
Great set of pens, ideal for a school or club
These pens, are really nice, easy to use, and look good. They work well, and provide a consistent ink flow regsardless of how it is used and treated. I have found them to be so useful, and beneficial for young individuals learning to write.
Perfect for schools, playgroups and parties
A Good Value large pack of mixed coloured pencils.
Perfect for parties or groups like cubs/rainbows, after school, etc. The Pencil's are good quality and dont easily break. The colour transfers to the paper well allowing colouring in of designs by the kids. Comes in a handy reusable box to keep them together
Perfect Highlighters
These were good value for money. Nice choice of colours, very smooth and they have lasted well..
