Setup, Compatibility & Care
Setup:
These cards require no setup. Simply take one from the pack, write your message inside, place it in the provided envelope, and address it.
Compatibility:
The cards are compatible with standard ballpoint pens, gel pens, and markers. It is recommended to test a marker on a small, inconspicuous area first if using a heavily saturated ink. The 5-inch square size is compatible with standard postage rates in most regions, though it's always advisable to check with your local postal service for specific requirements for square envelopes.
Care:
Store the cards in a cool, dry place away from direct sunlight to prevent fading. Handle them by the edges to avoid smudging any printed designs. If framing, use acid-free materials to preserve the card's condition over time.
