I adore these 'Paper Tape' hooks by Japanese designers Torafu Architects. Designed for the “Kami no Dougu” (Paper Tools) exhibition held by the “Kami no Kousakujo”, they were part of a project put forward by designers and print processing plants who were looking to explore the potential of tools manufactured from processed paper.
Designed to look like pieces of curled adhesive tape, the hooks are created by soaking paper, curling it, and then allowing it to dry in position; they’re actually surprisingly strong!
The tape hooks are incredibly versatile, just peel off the back and stick them wherever you fancy. They're available in three different sets of colours and retail in the United Kingdom via my favourite stationery store Present Correct.
