Card ships with loving handle and care. From 1 collector to the next.
I use a sleeve, toploader, easy to pull out tab, easy to peel off folded tape.
Raw cards come attached to cardboard for support, all nestled in a resealable sleeve to protect from water damage. Graded cards come covered with bubble wrap, as well as the resealable sleeve. All cards mailed in a bubble envelope.
If you buy multiple cards I combine shipping, and love to offer discounts depending on how many items you want. Returning customers are always well taken care of.
