We always recommend taking some luggage locks with you when travelling, not just to prevent people getting into your backpack or travel bag, but to prevent accidental opening of zips during flights and other journeys! Many travellers opt for a combination lock to secure their luggage, but this would mean remembering a code...If you're likely to forget your combination code, then key padlocks are the way to go! We've got handy twin packs available as well as TSA and durable brass locks.
Working well for me! I've applied for Polish plug converting to Japan, China, UK and it's really been smooth. I was looking long time for this kind of adapter and I'm relieved finally.
