Basic Shipping (7-12 Cards)

For lower-value orders, you’ll need these five things:

Insert cards into penny sleeves, don’t force them but most can hold three cards comfortably.
Insert the sleeved cards into semi-rigid card holders.
Fold the paper so that it will fit neatly into the envelope
Use masking or painter’s tape to attach the card holders to the inside of the paper, so that they overlap as little as possible - the cards must not overlap.
Address the envelope and confirm it matches the order.
Insert the card holders and seal the envelope.

You can then stamp & deposit the card holder directly into Canada Post mailboxes.

Semi-rigid card holders are machinable.
Tape ensures the card holder won’t move around, masking tape reduces the risk of getting a sticky residue on the cards.
Card holders provide a tight fit, so the cards won’t move around.
