18th birthday candle WELSH gift. WELSH candle. Penblwydd Hapus candle. Blueberry scented. Vegan candle. Welsh candle. Soy wax candle. Happy Birthday. Handmade in Wales, UK The enticing scent of blueberry The blueberry fragrances are blended perfectly with eco-friendly organic soy wax and poured by hand in my candle kitchen on the outskirts of Gower in South Wales. The burn time for this 0.3l candle is approximately 40 - 45 hours As soy wax melts at a low temperature it does not damage the glass so it can be used again after washing with soapy water. Other benefits of soy wax are that it is eco-friendly and vegan. It also produces a much cleaner flame than paraffin wax so the true scent of the fragrance can be enjoyed.
