 Chalkboard eraser  for easy cleaning

" peri-peri chalkboard eraser"







[Original Problem & Idea / Solution]

Every Japanese student has used a blackboard eraser. However, the trouble of chalk dust from cleaning the blackboard eraser could not be avoided even with the use of regular blackboard eraser cleaners.

My invention which I 've named the "peri-peri chalkboard eraser". The blackboard eraser can be easily cleaned by turning over the erasing part of the conventional blackboard eraser and using a new blackboard eraser like a corroborative roll.

[Specifics]

  • Clean by peeling off the erasing part, which is the blackboard eraser cloth!
  • Smooth cleaning in class and during tests.
  • Low-cost exchange if the body breaks.
  • Solved from the problems of sound, cleaning, and labor!

[Summary]

Many people, including students and teachers alike, have been troubled by the cleaning problems of blackboard erasers. However, this “Peri-Peri Chalkboard Eraser” will solve such a problem! It will surely become essential for a comfortable school life from now on.

    I hope your invention comes to fruition because cleaning chalkboards was such a pain for me for the last 12 years of high school.
