It is more useful than a round bottle because it is strong and easy to carry. It is okay to ship by courier as it is. However, as the price rose by more than 30% compared to when I bought it in January, I am thinking what to do in the future. I should have bought a lot! If there is such a system that you can notify in advance the price increase of the product with the purchase record, it will be appreciated because it is possible to purchase it quickly.
It was easy to use in a wide mouth. The price was cheap to some extent, but I feel like I could be cheaper. It is saved if there are indications that can be used at a glance such as acids, alkalis, solvents, fats and oils etc.
