O2 Supli

Was in the convenience store getting some grub when I noticed these things on the shelf – a closer look has me discovering that you can now buy cans of oxygen along with your bread, milk and idol magazines...

The product name is O2 Supli and contains about 35 puffs (each puff being 2-3 seconds) of oxygen.
Both products are aimed at folks who are stressed out - could be because of blog content that gets on their nerves besides other things. The green can has a minty taste and “refreshes the head/brain” while the blue can “refreshes the body”.
The price is 600 yen per can.
