This lampshade has a cornered outside and a curved inside. The curved inside is quite unexpected. Just like the first time you open a chestnut and see that it is very round and curved on the inside. This lampshade is folded with utmost precision out of 1 piece of special FSC paper of the type Butterfly. The strong folds and curved folds on the inside play with the light. The dimensions of this lampshade are: -18 cm height; -28 cm diameter.
