ItalyAmazing bag & perfect customer support
two years ago I bought two bags for me and my son - the Flak Sack is an incredibly sturdy, safe and the color is perfect. In November I bought two more bags, for my wife and my dear friend. The package was lost and customer service immediately sent another package with the fedex courier with a gift. Thank you
