The Vanaspati Diya batti is made from pure vanaspati ghee. The big size wicks burn for approximately 30mins. They are perfect for daily puja and by the time you leave home you're sure the wick has finished burning. Especially in homes that are made of wood, these serve the purpose and reduce danger to the home.
The wicks have a mild flavour which is a combination of camphor, sandalwood and jasmine. These ghee battis are a replacement for handmade ghee diyas, so there won't be any strong smells when you burn it.
These Vegan diya battis are wax free. After a wick is fully burnt, there will be a small black residue (cotton wick) left in the lamp. Throw it away and your lamp is ready for your next puja.
