- Perfect size and pack: scratch cards are 5 cm in diameter, with 50 pieces per pack. They are pre-cut to fit most cards and invitations for a clean, seamless look. - Easy to use: simply peel off the protective layer and apply the sticker to the desired spot. No tools required, ideal for quick customization on invitations, cards, and gift tags. - Durable yet removable: made of high-quality polyester resin and epoxy resin, these stickers adhere firmly but are easy to remove without damaging most surfaces. A thin protective layer keeps the area underneath intact and readable as soon as it is scratched. - Versatile: suitable for invitations, lotto tickets, greeting cards, and vouchers, and also great for birthdays, weddings, holidays, and many other occasions. They add a creative, interactive element to your messages. - Practical benefits: creates a reveal area that protects the underlying design until the moment of reveal, while ensuring readability after scratching and reducing the chance of accidental marks. - Use scenarios: - Wedding invitation with a scratch-off message for RSVP or a hidden note. - Birthday card that reveals a surprise gift or message. - Holiday card or voucher that reveals a discount or special lyric/message.
