Why is Vector Butane so good? Vector Butane is filtered 5+Times for highest efficiency. Quintuplus filtered premium Vector Butane gas refills are highly recommended for all hi-tech Vector and other gas lighters. Jet torch and turbo lighters require ultra pure Vector gas to produce highly efficient jet flames. Other butane gas is not filtered as much and will clog the internal burner cylinder and affect the performance of the lighter. Vector Butane Product Size: Width: 2"• Length: 2"• Height: 9". The contents is 320ml. If you have questions about this great product contact us sales@eg11.com. If you are a retailer email us for retailer wholesale pricing.
