Often see things I find interesting and think it might be of interest to others.
So I post the items here and make it easier when trying to explain the item.
The first image is of plastic containers stuck on a printer which are filled with cheap printing ink.
The containers are connected to the printing head with fine tubes, the old ink cartridges are not used.
This is a great way of avoiding the extreme prices asked for ink cartridges.
These containers are used on printers in school, police stations etc. throughout Asia.
