/cgl/ - Cosplay & EGL

Randoseru (ransel) are based off the rucksack styles that originated in the west, which were meant to be bags in general, not just for children.

The most common type of randoseru in Japan is the traditional shape you can see in Sutiblr's photos, which became part of the "uniform" for elementary school children. In Japan, they are associated with children. Because of that, you often see them used as a fetish symbol along with recorders in lolicon/shotacon works.

However, there also exists bags in the randoseru category that are just meant to be bags. They don't share the shape used by schoolchildren.
