The Rainbow Liquid Chalk Specialists are a company who sell the liquid chalk that can be applied on smooth walls, which makes it easier to write on, and have no rough edges. They do not have any other products besides the liquid chalk, but they also have a selection of colors to choose from, as well as a variety of different models. There are many reasons why someone would want to buy the liquid chalk from this brand. If a person is notoriously messy with their hand writing and does not want to spend an entire day cleaning up the dry erase marker residue, then this is the product for them. The other reason is if a person is in a writing competition and needs to do an entire day's worth of work in a few hours. Finally, this could be good for people who need something different than traditional whiteboard markers that they already have.
