4 memo ballpoint pens with 6 memo levels each with 24 symbols
Thanks to these four seemingly harmless ballpoint pens, which represent the entire reminder system with 576 symbols, you can recall all of the exam material immediately.
This means you literally have a huge library of the knowledge you have learned “under control”.
This makes forgetting or blackouts during exams almost impossible.
Please note that you need the memo levels from the complete system in addition to the memo ballpoint pens.
