Are the leaves real and what kind of a tree is the botanical leaf from ?

The leaves are commonly called the ‘seagrape leaf’ and come from Central & Latin America and Florida in the USA. Here is a weblink with additional information:

What sizes are the leaves ?

Each leaf in the box has a min size of 15 x 17 cm

What is the fragrance coating on the leaf ?

Pure & concentrated crystallised perfume, a modern form of “Enfleurage”, the oldest perfume extraction method, and contains up to 40% of beautifully pure perfume (patent pending).
Each precious leaf is carefully coated by hand.

Will the leave break when the fragrance coating is running out?

The leaves will not break. All the happens is that gradually a very thin grey film appears. Many of our customers continue to use the leaves to decorate their home long after the perfume is finished.

What is the plastic foil sachet made from ?

A special aromabarrier foil (PET / EVOH). This material biodegrades.

Any special instructions ?

Ignoring instructions for use may lead to property damage or personal injury. Do not eat. Keep it out of reach of children and pets. As wax can melt, place away from direct sunlight and sources of heat (e.g. radiators, lightbulbs, TV's). Handle with care and only with your hands. Always wash your hands with soap and water immediately after touching wax and before touching anything else (e.g. eyes, mouth). Should this accidentally happen, immediately rinse with clean water and consult your doctor. Do not let the leaf get in direct contact with any fabric, polished, painted, plastic or wooden material which may be damaged by perfume oils.
