How much guoelephant Super Glue is in the bottle and why is it half full?

　　Each bottle of guoelephant Super Glue contains 15 grams of adhesive, though the bottle is only half full.
　　For high performance and usability the adhesive needs to be protected from air. One way keep the air out of the adhesive is by packaging in thick plastic bottles. If the bottle was completely full at 15g, and still the optimal thickness, it would be too hard to squeeze.
