Here's what a seasoned buyer would tell you:

• If you're gifting a mug, pick one from a brand that uses a rigid box with a molded insert. It's the safest bet.
• For soft goods like t-shirts or totes, a poly mailer is fine—but check that the fabric isn't wrinkled beyond saving.
• Always include a note. Even if the packaging doesn't have a card slot, a small handwritten note taped to the inside of the lid makes it personal.

And one more thing: don't judge a brand solely on packaging. Some of the best coffee merch comes in minimal, recycled packaging that's still protective. It's okay to trade a little flash for sustainability, as long as the item arrives safe.
