The AF Tank 4ml Bubble Glass by Aspire is a specialized accessory designed exclusively for the AF Tank and the Rover Plus Kit by Aspire.

This bubble glass allows you to upgrade the e-liquid capacity of your tank from the standard 2ml to a more generous 4ml.

This increase in capacity means you can enjoy longer vaping sessions without needing to refill as frequently, adding a layer of convenience for users who prefer extended vaping sessions.

The bubble glass design also adds a unique aesthetic to your setup, giving your tank a distinctive look while enhancing its functionality.
