Any of the custard combinations works for my lovely wife and I. We have been vaping for many years now. I've tried other flavours and I keep coming back for more custard. Custard and custard with added custard. That's what we love. That creamy back taste that lingers. We both mix our juices with under 1% of nicotine. Just enough to know you've had that nicotine hit but not enough to do any harm........I have also got to say, one 10 ml Unicorn tears @ 1.5of nicotine tipped into a 50ml of anything custard and I'm in heaven......I love your mixes. Thank you very much to everyone at REJUICED. You are the best!
