Aluminum is a lightweight metal with excellent rust resistance. Therefore, it is very suitable for making jars for storing candles. These candle jars are constructed in a seamless structure with a black covering. The round aluminum tin cans are stamped in one piece and seamless, so there are no side leaks. The screw-on lid is easy to close and open. And it comes with a foam pad to double strengthen the leak-proof effect. These are 9 oz candle tins and they are 101 mm high and 83mm in diameter. They feature a flat top, which not only allows you them to stack neatly, but also allows you to put a cute label on them. Our aluminum tin jars can come in handy for a variety of occasions. You can use them not only as candle containers, but also as storage jars for crafts, lip balms, samples, screws and other small parts, etc. Once you purchase our tin jars with lids, you are entitled to a 30 day worry-free refund.
