This handmade pebble is created from porous clay which will absorb the blend of essential oils provided by Halka B Organics. Approximate size: pebble 5.5cm x 2.5cm / wood saucer 6cm x 1.5cm. Total size: 6cm x 3.5cm / 6 ml essential oil bush blend glass bottle. Pop a drop onto the pebble and the aroma will be carried throughout the room, cupboard or even in the car... The saucer complementing the pebble I only stock it now in light colour as this one comes from a sustainable source Anacardium tree. A note about the use of essential oils: With a pure essential oil there are several qualities that I believe they offer beyond their fragrance, their main job is to be absorbed into our system by breathing it, to promote health and wellbeing.
