Following the acquisition of a blackboard glass I had to acquire suitable markers, and have discovered the "chalk markers." These products are very good, very bright colors and fit perfectly. Not having tested other lines, I could not tell if they are better or worse than others (although it seems complicated to do better), however one thing makes all the difference; The stationary island of customer service is so on its product they contact their customers on to find out if they have the satisfaction of these. They take the time to answer the questions you have (by developing - for a product as "basic" a marker that's rare, many high tech boxes should imitate) by not fear propose possible solutions they do not offer themselves - which is for a company the final frontier of customer satisfaction. Other companies are they better? I do not know, and could not probably not seen that I intend to test their range of dry erase markers and take other peaks widths futures for their different ranges and colors, given their assurance about their products I have no reason to test wills other manufacturers. These markers satisfy me completely and I even now serves for other purposes, for example they allow yourself to take benchmarks easily on complicated surfaces properly mark without damaging them as PVC window frame (when blinds poses particular).
