Please read the profile before commenting. These are German flasks that guarantee accuracy. They do not have glass stoppers. Each has a price tag of ¥4378. They have been stored at home after purchase. Specifications: Material: DURAN (borosilicate glass) Capacity: 250mL Accuracy: ±0.25mL Height: 220mm The photos are adjusted as much as possible to resemble the actual product, but please understand that the color may differ from the actual product depending on the environment in which you view it. I have confirmed stains and dirt, but please forgive any oversights other than those mentioned. These are items stored by a private individual, so please purchase them if you understand this. The packaging will be simple, reusing recycled materials. I hope to have a good transaction with someone who is comfortable with this price.
