How is the person pronouncing forvo.com/word/%E6%9B%B8%E9%A1%9E%E8%A2%8B ? It sounds like するいぶくろ　or つるいぶくろ but I was expecting a pronunciation of しょるいぶくろ for the word 書類袋

@snailplane Thanks - it's probably the result of listening too much to Japanese from English speakers learning Japanese, and not enough from actual Japanese speakers.
