50ml of nicotine-free e-liquid, presented in a 60ml bottle.
The Stonewall range are high-flavour strength, zero nicotine e-liquid products with a VG/PG ratio of 69/31.
To reduce the flavour strength down to our standard level (recommended), add 10ml of a 75VG/25PG solution and shake thoroughly. This process will result in 60ml of 70VG/30PG liquid.
You can find our 75VG/25PG Top-Up Solution here.
