I’ve done it a few times. You can google it, and there are some good guidelines. If bottle, I taped the cap. Then, whether can or bottle, I tightly wrapped them with small bubble wrap and taped closed. I used a box for multiples. Put them in as tightly as possible and fill in with bubble wrap or newspaper. I would recommend shipping FedEx ground if it can get there relatively quickly. I think mine all got there for proper consumption. That’s my amateur advice.
