Satellite Crayon Project + TIGER

What color is the ocean?

Inspired by the colors of the earth photographed from space, Ocean Crayons (SKY Perfect JSAT Corporation) were created in the hopes that it will allow users to learn about and play with the colors of the earth so that their love for the earth will grow.
These twelve colors were selected from satellite photos of the earth. They don’t have names, but they do have a reason.
Our new Vacuum Insulated Bottles were inspired by five of these colors.

A portion of the proceeds from the sale of the MCS-A50J Vacuum Insulated Bottles (for cold drinks only) will be donated to the Republic of Kiribati for use as a natural disaster fund in the face of rising sea levels.

Carry your favorite ocean color


On the front of the main body of the bottle, the coordinates (latitude and longitude) of where the ocean colors were photographed are indicated in the same way as the Ocean Crayons.
The two designs on the back are the logos of Satellite Crayon Project
and Tiger to indicate our collaboration.
