Review on D.E.Eco Tri-Corner Plastic by Austin Arvayo

I use them for bulk propylene glycol and vegetable glycerin. You can improve the design of the filling, since it can spill. They don't take up much space, which is very convenient. The inscriptions are really difficult to read, especially when they contain clear liquid. I have to read the fill line and hold it with my fingernail so it doesn't overflow, but they get the job done.
