Because of their wide range of colors and patterns, customers enjoy using them for wrapping, interior decoration and art works. MT masking tape’s promotional limited exhibition called ‘mt ex’ travels Japan, this time it was held in Hiroshima. The location was on the seafront, I tried to design the space to welcome customers who use the harbor. I taped ‘mt’ on the deck in front of the shop and covered the massive space with colored stripe. This approach succeed to exhibit customers the mt’s new possibility. I also covered the wall by mt’s new collection, so that customers are able to browse them and chose the tapes easily.
