Convert your 510 Thread pen to an ego capable pen.

The 510 – eGo adapter will make your battery/ mod more versatile, by allowing you to fit more atomisers and tanks to your device, which normally wouldn’t fit

For instance from experience we know a Kanger T3 won’t fir on a Vamo, as the Kanger T3 skirt, is too wide to fit in the crown of the Vamo, though the 510 – eGo adapter will enable you to fit a Kanger T3 on to  the Vamo or any other 510 battery or mod with similar measurements
