Packaging Design Toothpaste Packaging by Kazuo Fukushima The Toothpaste packaging design idea is a watercolor tube. It reminds the fun of choosing colors when painting. The Toothpaste is a unique combination of natural ingredients and amino acids found. Therefore, the upper half of the Toothpaste packaging is a natural expression, and the under half is a science and technology expression. It is a design that combines two different elements into one. Finally, the brand mark combines two toothbrushes in the shape of a cross to simply design the insurance oral products.
