Tiny but Mighty Size matters when it comes to disposable vapes, but so does performance. Since its launch, the DS01 series has been the true embodiment of a convenient disposable vape without the slightest compromise on performance. Now with its newly updated variants, the DS01 series further resolves shelf-life battery concerns and is even safer and easier to store. This pen-style disposable is available in 3 popular tank sizes while maintaining its super compact size. The newly released (-US) line further minimizes its size to make storage and transporting easier. To eliminate the worries of having a drained-out battery with unfinished oil, the new (-US) line also introduces a micro-USB rechargeable port to its tiny but mighty body.
