"For high performance and usability, the glue needs to be protected from moisture, therefore, we package our glue in thick plastic bottles.
If our thick bottle was filled completely full, it would be extremely difficult to squeeze the glue from the bottle.
Our bottle, which has the required thickness to keep moisture out, contains the stated number of grams of glue as labeled, and allows the glue to flow, making the product easy to use.
The amount you have described being in the bottle is the standard amount, under half full.
If any more glue was in the bottle consumers wouldn't be able to dispense it.
The standard small metal tubes usually contain about 3G and are for single uses as they won't be protected from moisture in the air and will harden whereas ours are 15G and the thick bottle helps prolong the life of the Super Glue so it can be used multiple times when the aftercare directions have been followed."
