i work for usps and in an area to help orchestrate fastest delivery of everyone’s stuff. i started DIY primarily because of the steep vape shop e liquid prices. i was also curious about the craft of creating e liquid and wanted to make smooth vapes with very little PG and zero throat hit. have had some disastrous liquids and also some very fines ones. it is getting easier now compared to the beginning yet great to know i can always call on ELR when a mix flies far south.
