I found this accidentally after using halo cartridges for years, which have now become obsolete.I tried the menthol 1.5 refills to begin with but I wasn’t keen on the taste so I switched to mint breeze.These are fab !!!£9.99 for a pack of 5 cartridges lovely flavour last a long time too.The postage is reasonable could be better if it were free though.If you’re thinking of quoting give them a go I smoked for 25 years and I’d never go back to normal cigarettes. £9.99 for a pack of 5 e cig cartridges, 3 different strengths and loads of different flavours. Glad I found you smoko !!😊
