Matsumoto Kiyoshi is the biggest drugstore in Japan. Think of it as a German DM or Rossmann on steroids. When I found them in Tokyo, they would often be on two levels absolutely packed of products. You would barely have space to move in the aisle.
When I was in Bangkok and went to the famous MBK Center, I absolutely freaked out when I saw a Mastumoto Kiyoshi. It was rather small and did not get that feeling of crowdedness, but it still had many must have Japanese beauty products.
I really had to replenish my stock of sheet mass, this was the perfect opportunity. Ordering sheet masks online is possible but shipping can take 2-3 weeks; then there’s shipping fees and sometimes, even customs fees. So when I saw the opportunity for bulk shopping of sheet masks, I took it!
