I purchased these new two years ago and used them to raise beetle larvae. I bought the 2300ml containers for ¥1380 each at the time. The 2300ml containers are 15.5 cm in length, width, and height. I've also taken photos to show their size with a scale. I washed them thoroughly, but there is some staining. I appreciate your understanding. I will also include 13 sheets of Tyvek paper.
