The standard compound cards are 70mm X 70mm - the same size as the square cards in the board game Power Grid.
The larger cards for the Lab Partners Inspansion are standard "tarot" size cards - 70mm X 121mm.
Plastic sleeves for both card sizes are readily available from companies such as Mayday Games and Fantasy Flight Games.
Sadly, no. A wooden box would be prohibitively expensive. However, we may create a custom pledge level that provides a wooden box for the collectors out there...
Very easily! You simply add to your pledge the amount of the pledge level for each additional game you would like.
For instance, if you are pledging at the CHEMISTRY 101 level and wanted three copies of Compounded, your pledge would be $42+$42+$42=$126.
