How should I care for my candle?
Trim the wick to ¼ inch before each use to prevent excessive flame and soot. Our candles are made with paraffin wax and cotton wicks for a longer-lasting burn and a strong scent throw.
How long do the diffusers last?
Our reed diffusers last around 8–10 weeks, depending on room temperature and air flow.
How can I make the scent last longer?
Turn the reeds every 12 hours to refresh the fragrance, and replace the sticks every 4–5 weeks for the best scent throw.
What makes KLH diffusers special?
They’re crafted with a premium blend of DPM (Dipropylene Glycol Monomethyl Ether) and a high concentration of fragrance oils — ensuring a strong, long-lasting aroma that fills your space beautifully.
