THERE’S NO PLACE ON EARTH BETTER THAN JAPAN REGARDING MANHOLE COVER ILLUSTRATION. THERE ARE THOUSANDS OF UNIQUE COVERS THROUGHOUT THE COUNTRY, FROM TINY VILLAGES TO METROPOLISES. HERE WE CELEBRATE FOUR OF THE LARGEST CITIES IN JAPAN-TOKYO, KYOTO, OSAKA AND NAGOYA. Manhole covers from around the world permanently etched into functional art. Each set of these sustainable cork coasters come with four unique designs to best remember one’s glass. All are fabricated in Philadelphia with upcycled packaging. Retail racks included for first-time orders. Who buys these? Tourists as these are perfect souvenirs and are lightweight. Holiday shoppers purchase these as they make perfect gifts. These are also acquired as housewarming, birthday & anniversary gifts. Cork is the perfect coaster material as it is water-resistant and is less likely to cling to the bottom of glasses.
