Portable dry-herb vaporizers are challenging to source here, mainly because of the lack of demand. Now with great flower beign available, this will change.
These three vaporizers (Pax 3, Da Vinci, Apollo) are awesome, and available for purchase from other countries. Other than USPS, there are no bans on li-battery devices. So you could buy one from the U.S. And there is no ban in carrying this on an aircraft.
You can also source lower/mid-range options from AliExpress, I've ordered Airistech devices from them, and they get delivered here.
I have seen a few local options as well...

I think we'll see more availability here in the coming months.
Just a little research would lead folks to understand the benefits of a dry-herb vaporizer. Probably the best, safest, cleanest, healthiest, most discrete portable method, other than dabbing fresh rosin, to enjoy quality cannabis.
