Betula also called Birch pollen. Birch pollen is one of the main trigger of hay fever.
Pollen is everywhere. Also at home.
Please note that the light fixture is not included in your purchase. The cover lid of your lamp is optional and has to be purchased separately. We leave it up to you to buy a Bulb of your choice. We used LED Bulbs, in the picture above, to give the lamp different colours. We recommend LED smart Bulbs like the Philips Hue White and Color E27 Starter Set
