Convenience blackboard er / Office products

Convenience blackboard er

Many problems exist in the usage of blackboard erasers in school, for instance, some students are too short to clean the top of the blackboard while some teachers have to stoop low to clean, which have bothered a lot of teachers and students for a long time. We design a 45°slope for the blackboard eraser according to our holding habits so that we can clean the blackboard more comfortably with the slope-model product. The shell is made of plastic with various colors, which is pretty and portable for users.
