‘mt’ masking tape’s promotional exhibition “mt ex” is held all over the world.It was held in Kumamoto in Kyushu from 15 March 2013. We designed the space by covering with ‘mt’ tapes and show customers the new possibility of it’s usage. We choose a huge old depot for the exhibition and decorated the floor and the wall by ‘mt’ tapes. We hanged a thousand of balloon-lights made with ‘mt’ Washi paper from the ceiling on the first floor. The aim of this exhibition was to show customers many aspects of ‘mt’ tapes through these unique experiences.
