As long as your vendor is legit I say it's safe. Who checks the mail? A little powder in an envelope looks like an envelope. A box looks like a box. Not drugs.
Where is the best place to find vendors shipping from the US and located in the US. My shit has gotten seized twice now in the last year coming from overseas. You think these mother fuckers returned my butcoin. Hell the fuck no.
Trap House will be open soon. It will be more trusted and good. If not delivered you will get the coin back. You should have got it back if you ordered correctly on another site. Never FE.
