The standard paper that our cards are printed on is a high-quality heavyweight (120 lb) Eggshell finish, ultra white card stock. If you would like to upgrade to a heavier weight or a higher quality paper, the prices are listed here.
The Cotton 118# is not quite as heavy as our current 120 eggshell card stock, and has a similar texture, but it is a higher quality paper.
The double-thick card stock is VERY thick. Typically this is for coasters.
