All disposable vapes, including Geek Bars, are made of the same components as a standard, refillable e-cigarette, but without the nicotine. A tank holds the e-liquid and a coil that heats up to create vapour, powered by an internal battery. We only work with the most reputable and trustworthy manufacturers and we only buy from officially-licensed suppliers. All of the products we sell are fully EU TPD and UK TRPR compliant and we can provide full Material Safety Data Sheets upon request, just get in touch via our contact page. For the latest up-to-date information on the safety of e-cigs and vaping, we recommend the NHS Live Well site.
