Nyanko lock and DIY padded camera inserts (made from really old board shorts and foam) for my black bag.
Most importantly, the thing to prevent easy pickpocketing when travelling: a carabiner on the bag’s D-ring to hook the bag zipper onto. Totally got the idea from Pacsafe anti-theft bag zippers but it definitely works wonders for peace of mind. (The Nyanko lock was just a step up on the carabiner, and I only used that at night or on the flights.)
What’s in my travel bag: glasses (though off flights I mostly used contacts), powder pact, multi-tool (lifesaver!), scrunchie, tickets, necklace, medicine pouch, card key, wet wipes, tissue, moleskine sketchbook, pencil, sketch pen (sans wallet, passport and the camera that’s being used to take the shot). F
orgot to put the iPhone there as well….
Train tickets, d’Orsay exhibition (free museum day), boarding pass and hotel key.
