The Slydr-L is the first of 5 tanks sigelei is planning to release. It is a very durable, hefty tank that hits hard. It has a Slydr cap for easy refill and holds 5.5ml of liquid. Made of food grade stainless steel and has a very nice big bottom air flow. Also a Velocity style rebuild deck. I am a major fan of this and look forward to it hitting the market. Keep your eyes out for it. Vape Strong!!!
