While we appreciate your desire to prolong the life of our Eco-Luxe bamboo candle vessel, we must prioritize your safety. We cannot condone refilling the vessel with additional wax due to the potential fire hazards it may pose. Our bamboo vessels are carefully designed and treated to ensure their fire-resistant properties, and tampering with them can compromise their integrity.[BR]However, we encourage you to explore other creative and sustainable options for repurposing your vessel once the candle has been fully enjoyed. Consider upcycling it into a charming planter, a stylish pencil holder, or something equally delightful. Embracing the spirit of eco-friendliness, you can also recycle the vessel or dispose of it in your personal or local composting facility. Should you have any other questions or concerns, please read our blog post on this matter, or feel free to reach out to our customer support team.
