WARNING : Occasionally the diffuser liquid may absorb into the string past the wooden lid. If this happens you must be sure the string is hanging from materials that won’t be affected or damaged by the liquid soaked into the string. Hanging diffusers should not be left in high heat environments exceeding 30C. Clean up any spills immediately. Diffuser fragrance oil may damage (but not limited to) surfaces like plastics, polished/varnished surfaces and wood. No responsibility will be accepted by Hey Pretties for any damage caused to any property caused by improper usage/spillage.
