Bolsius tea lights provide comfort in the home. They have a burning time of up to 4 hours. Made with natural vegetable wax from Europe, without palm oil. They do not smoke or drip. We use local vegetable wax, eco-friendly packaging, and fragrances with natural extracts to improve our ecological footprint. Safety warning: Always place tea lights in a suitable container with adequate ventilation. Avoid direct sunlight and keep them away from flammable materials. Straighten the wick before lighting and use a candle cover to prevent splashes.
