MUJI

Japanese chain Mujirushi Ryohin aka MUJI has made a name for itself in the design world by removing the name or brand from their designs.
In English, Mujirushi Ryohin translates to "No Brand, Quality Goods". According to MUJI,"the company’s basic principle is to develop new, simple products at reasonable prices by making the best use of materials while considering environmental issues". They get to the core of each item's purpose and function. You won't find any bells and whistles. Just simple, clean lines.
You can find MUJI products through their UK store, or through Muji at MoMA.
Some of my favorites are:
cardboard speakers
wire key ring
cup and saucer
pen pot bookend
playing cards
