A closer look
Picture the cord, not an endless reservoir
Imagine someone repeatedly interrupting a colleague during a task. At first the colleague replies quietly; after another interruption, the reply becomes sharp. The idiom can describe that change. This is an invented language example, not a suggestion that anger proves someone was right or that others should have guessed an unspoken limit.
Notice the difference between describing a feeling and prescribing behaviour. A narrator can say patience finally ran out, while the person involved may still need to explain their reaction. The picture of the snapped cord makes the moment memorable; it does not tell us everything about the disagreement or decide who should apologise.
A meaning to make your own
忍 has meanings involving enduring or concealing. [2] The character does not require unlimited tolerance. Wearing it can reflect your chosen connection with composure, while the longer idiom reminds you that words about patience also describe its limits.
A thought to give
If choosing 忍 for a patient friend, thank them for something specific: “You gave me time to learn that first difficult step.” Avoid a note suggesting they should silently accept every future demand.

Is 堪忍袋 a piece of ninja equipment?
In this idiom, the bag is a figurative image for patience. [1] It is not presented as historical equipment. Learning the full expression helps prevent a familiar kanji from leading you toward the wrong story.
