The pros:
- It writes well on white boards
- It is very readable for students
- Must take months (compared to table felts, it is incomparable)
- No felts History spackling
- We can lend to students who do not have a slate felts
- There are colorful
- Pencils are big, so much resistant
The -:
- It takes a damp sponge or cloth to erase (erasing very simple), and when one has no water in the class, it is not very convenient. Colleagues have told me with a damp microfiber cloth
