The Utillian 5 replacement coil pack comes in 2 configurations: Triple Titanium or Twisted Kanthal. Both utilize black ceramic and come with 2 replacement coils per pack. These coils are identical to the ones you originally received with your Utillian 5 and should be replaced when you notice the flavor of your vapor degrade.
Utillian 5 Atomizer can be found here.
*Twisted Kanthal Coil is currently out of stock until February. Sorry for inconvenience.
