My tealight six pack comes in polycarbonate cups which are heat resistant and also reusable. They come in neat little boxes. Beeswax burns longer, brighter, are hypoallergenic, and non-toxic. My wax is always 100% pure rendered with no additives. Trim wicks to 1/4 inch at the start and each new lighting to avoid a large flame. Large flames can trigger smoke. Drafts can cause your beeswax candle to smoke despite being smokeless. Never leave a candle unattended and my recommendation is to place the candle on a plate in the center of a table so it can't fall off. It's better to be safe than sorry.
