Travel Gear for Upcoming Trip (Paramus)

Hi everyone! I’m currently planning a trip to Europe and trying to gather a few travel essentials. Before I head out and buy them brand new, I wanted to see if anyone has any of these items sitting around, unused, and would be willing to part with them?I am looking for:
Binoculars (for sightseeing)

Luggage scale (to avoid those strict airline weight limits!)

International Travel Adapter & Voltage Converter (so I can safely plug in my electronics over there)

If you have any of these gathering dust and are happy to gift or sell them for a reasonable price, please let me know! I would be incredibly grateful.

Thank you so much in advance!
