You can buy razors at a beauty store for a relatively cheap price. Mirrors you can acquire various other places, and I would just use a plastic straw for snorting. Reason being, when you're done with your drugs, you can slit open the straw and scrape outside what got stuck to the inside of the straw. %)
I'm going to close this for now because it's not an OD topic, and I don't really think stuff like that is commonly sold online. Sorry.
