There is a weird satisfaction that comes from making a package apocalypse proof

. The post office lady’s laugh at me often

^^^Same here vvv, haha...
My neighbor, a retired USPS clerk, gave me a few tips to mitigate nosy postal workers who might want a little "look/see" into your parcel. His best tip was to
apply some unusual novelty tape on the flaps. Postal workers have access to oodles of common packing tape, but the outlandish tape designs can make some think twice about messing with something they would have a more difficult time covering up.
I've used bacon novelty tape from the big river site for a long time now <even before Busse did it themselves, btw

> to tape down seams. Clerks used to ask me if it was "scratch'n sniff."
There's also little holographic "Tamper Proof" stickers that are very cheap that I use sometimes.
It's a delicate balance, however, between making your parcel look low-key protected mode vs. making it a flashing neon sign "STEAL ME = VALUABLE SWAG INSIDE."
Some hacks he gave me that aren't visible from the outside:
pack with stuff that falls out and makes a mess like shredded papers or confetti.
Last stealth tip shared to me:
tape the goods to the inside of the box so it can't be secreted out easily.
Unfortunately, as one of the members above already noted, some of the tampering countermeasures
make it more difficult <
read: aggravating>
for the buyer to open their parcel.
Although I've had a couple entire packages get straight up jacked before touchdown and had to be turned into Paypal-- I've never had a blade I sold arrive MIA from it's package with just the hull of the package arriving.
But, conversely I have had a couple BF members cuss me out for making the package to hard to get to when they were in the midst of blade fever.
Mission accomplished, I guess.

sorry so long, but if it helps some members, maybe it was worth the time.
