The package reached the Canary Islands (Spain) within 30 days. It was delivered in a clear, separate bag, and was well put together and secured. The nut mechanism can be adjusted to fit any watch. I tried it, and initially, I could open the watch case without any significant difficulty. It held perfectly, and the outcome was great. This is a worthwhile purchase, and I recommend it if you want to replace watch batteries yourself to save money. It's worth mentioning that watch repair shops frequently charge a considerable amount for this service, which is something you can do yourself.
