Christmas mail thieves, hope you're happy

So I have a friend whom I've known for almost a decade now. We're online friends but we're closer than most irl friends become. I know she had wanted a DS for years and I had shown her pictures and videos of my DSTWO way back.

Fast forward to Christmas 2017, and I spot a DSTWO for sale in the Trading Area of this forum. I thought it would make the perfect gift for my friend. The kind Temper gladly sold it to me with a discounted price as well as provided a microSD card. I received it and got to work with setting it up for my friend, adding all the games I thought she'd enjoy as well as all of my save files for her to be able to "explore" my childhood with the DS (using the DSTWO's Save Slot feature which allows for up to 4 individual saves per ROM).
I even loaded it with some songs and videos for her to test media playback on the DSTWO. Not only that, I recorded the entire process of me setting it up on the computer as well as testing it on the DS, edited them all, and sent them to her, which made her really look forward to receiving the card for Christmas. She had found a couple cheap DS systems locally and was planning on picking one of them up after receiving my package.

She received her package today. With a torn hole in the envelope. The DSTWO and microSD were stolen, among her other mail. I don't think I've ever felt such sadness before: this meant so much to her, to us. She would have finally been able to experience the DS library, with all of its wonderful games. But some jerk decided it was better off with them and just took it.

Here's a pic of the packages' contents:
The bubble wrap folded over at the crease to ensure the contents would arrive safely. The DSTWO and SD adapter were put in the DS game card + SD card holder that the kind temper dudenator sent them in, and was taped to the bubble wrap to prevent it from shaking during transit and ripping through the envelope.

Here's how it looked when she got it:

Some of her other mail had also been stolen. It truly pains me to hear this happened to her, especially on Christmas. This is the first physical item I've ever sent her, a gift that would provide hundreds or even thousands of hours of entertainment for her, and all she got was my Christmas card (which I'm grateful wasn't also stolen.. SMH).

I've already promised her I'll get her another DSTWO, but.. how? How will I do that? How will I get it to her without it being stolen again? Will putting it in a box help, or will it make it even more likely to be stolen, as usually more valuable goods are shipped in boxes? DSTWO cards are super hard to find, too, and I only want the best for her..

I've never had this happen to me before and have never heard of it happening to anyone I know either. Maybe it's because I'm Canadian and the stereotypes about us are true when it comes to being polite and whatnot. Maybe I've just been lucky. Maybe this is just as unlikely to happen where she lives as it is here and she just got very unlucky. All I care for right now is to get her a replacement.
I had made a backup of the microSD just before I shipped her package so setup of a new card is not an issue at all. I just need to find another DSTWO and figure out a safe way of getting it to her this time.. Which I honestly feel shouldn't have to be a precaution that has to be made in the first place.

Thanks for reading my rant. I hope you all had a more fortunate Christmas. And if not, feel free to share your stories. And know that for those in the same situation as my friend and I - or worse - I truly know how it feels and hope somehow something good comes of the situation.

UPDATE: It has been brought to my attention that it is more likely the rollers at the post office are the culprit here and not mail theft. I now know I should have sent this in a bubble mailer. I at least feel better about the situation now and am more hopeful on getting her a new one. My hunt begins now..
