Check the labels on items that seem to be marketed as locally made and sourced. What may seem to be a craft item only found in the area could easily be a mass-produced look alike item made to look like the real deal. Try to find local artisans and craftspeople to buy your souvenirs from, as these places will offer much more authentic pieces and help support local businesses in your destination.
When you’re in a new place you’re not quite familiar with, it can be difficult not to fall into travel scams and tourist traps with how easily they can target you. The best protection against them is being aware and vigilant of what is going on around you and knowing the most common types of cons out there so that you can avoid them.
