The sisters' solar lamp is made of glass, iron, ABS and polysilicon and measures 15 x 13 cm. With the handle, it measures 24 cm in height.

"Light up your balcony or windowsill with this beautiful little solar lamp," Anna suggests.

The sisters kindly note that the lamp does not tolerate direct sunlight over 30 degrees heat or frost. It should also be shielded from direct rain. The required AA battery is included.
