As they said in this chapter, the power depends on size and precision.
That's only if they're using the same kind of magic ink, no?
The ink is what makes magic works in the first place, since afaik, even if you draw glyph using normal ink, it won't work.
I mean, the first incident happens because our MC decided to use the freebie pen with ink included when she draws the glyph.
Also, I just noticed that the author foreshadowed the whole blood-as-ink stuff. Neat.
