Why do we sell coffee beans in light-proof bottles?

It has started raining. I feel that the days warmer are increasing in Fukuoka.

By the way, our shop sells coffee beans in shade bottles.
We told you who bought coffee beans, if you can bring a bottle the next time you’ll buy coffee beans (if there are no scratches) you will get a discount of 150 yen to 200 yen.
Of course, we will give you a clean bottle instead of filling the empty bottle you brought. (We will boil, wash and sanitize the bottle you brought and reuse it.)

I guess everyone is experiencing it.

There is a limit to what each person can do, but still small things can be. Let's get started.
We start with what we can do.
