Esco Bar is a popular brand of disposable vapes sold by Texas-based Pastel Cartel. Ready to vape right out of the package, Esco Bars come pre-filled with nicotine salt e-liquid in 5% (50 mg/mL) strength, often from well-known vape juice brands like Fruitia, Ripe, Noms, Kilo, and Aquios’s H2O e-liquid, which is partly water-based.
