Fast delivery, great backpack


Comments about the backpack itself can be found online, I just received it, so I will write about the delivery. I was very worried about the site’s account, because for Russia the prices were more than 30% lower, which raised suspicions, plus not very perfect reviews about the site on the Internet I’ve been reading .. In general, the order came 4 days ahead of time, which pleased me, packed well, and the thing is original, well-made, without flaws.
