This is Paperglass. I recently purchased it. It's thin and convenient to carry, making it good for travel. I'm also including the warranty. It's 2.0. ¥17,600 (tax included) Paperglass was born in Sabae in 2012, and initially, it was delivered directly to each customer through online sales. It has received four design awards, including the Good Design Award (BEST100), both domestically and internationally. To date, over 150,000 pairs have been delivered to customers, and now they are beginning to reach customers around the world.
