Mechlyfe Slatra RDA $19.79

The Slatra RDA by Mechlyfe and AmbitionZ VapeR sports an overall diameter of 25mm alongside a height of 30mm. In addition, you'll get a resin wide bore drip tip which will match the actual color of the atomizer. It is an 810 size, so you'll be able to use your other custom drip tips if you'd like. Also, it does include both a standard, and BF 510 pin, so you can use it on your squonk mods as well as any normal mod. Mechlyfe's Slatra does feature a step down honeycomb airflow design, so you'll not only get a buttery smooth draw, but excellent flavor as well.
