Go to Health Cabin or Heaven Gifts. Look up any product made by joyetech (eleaf is a subsidiary.) You will see a disclaimer that they cannot ship those products to the UK, South Korea, Italy or Russia. (Italy and Russia are missing from some. Maybe those countries are new to the list.)That can't be entirely true. It might be true for certain products.
Examples:
Joyetech eGo ONE Mini Kit
50W Eleaf iStick Full Kit with OLED Screen MOD Battery - 4400mAh
