Himalayan Crystal Salt Lamp - Pyramid shape

Himalayan Crystal Salt Lamp are made from pure crystalline salt sourced in the Himalayas. The lamp emits negatively charged ions as it warms up. These negative ions neutralise the electromagnetic radiation (positive ions) produced by your household electronics. They also help to purify the air, clearing away dust, pollen, allergens and smoke.
