A hard-to-break oriented PP bottle with transparency similar to that of glass.
The bottle adopts a special graduation so even if a label is put on top of the graduation, the projection of the graduation line will not be bothersome.
There is no inner stopper and shuts out any liquid leaks.
The contents of the light blocking bottle can be seen while having a UV transmittance of 0.3% for UV of 400nm or lower.
