It has been stored at home, so I would appreciate it if you could understand.

Outlet with an inner diameter of 16.5mm / Soft material The large diameter prevents residue from clogging and allows for quick discharge, significantly reducing discharge time. The soft material makes it easy to squeeze out. 2. Large tabbed cap The large size makes it easy to open and close, even for those with dexterity issues. 3.
