I have always thought that internet is always needed to send bitcoin or other cryptocurrencies. It's my first time learning that it could be done offline.

Check this article https://www.cryptovibes.com/crypto-news/bitcoin-transaction-shortwave-radio/

maybe sending offline can be done but it's not as fast as online, and obviously this has the risk of being hampered by shipping, I think this is very uncomfortable

I agree. It is uncomfortable to used bitcoin offline because as you can see even low fees make the transaction lose, what it can do if it is offline. Fast transaction happen when you use internet and it sure going to transfer safer than used offline. I salute those person who are developing this such offline thing it is become successful and work faster without being delay or lose of data.
