510 Cartomisers - hard tipped (Suits 510 and ego threads)
Pack of 5 cartomisers- Colour: Black
Cartomiser's are really a simple to work, one part device. They have been made to make the 2 part (atomiser + cartridge) into one part.
A one part cartomiser make the 510 or ego a more sleek solution. A lot fewer components means that it's easier to make use of.
These are typically theoretically disposable, however you could get away with filling them up quite a few times.
