Great design, slightly small envelope

The card itself is beautiful and the message space is generous. The envelope fits snugly, so be careful when inserting the letter. Overall, a great purchase for a graduation gift.

Elegant and meaningful

I bought this for my niece's coming-of-age party. She loved the sophisticated look. It stands out much more than standard drugstore cards.

Nice but expected more sheets

The card is lovely, but I thought the set might include extra letter papers for drafts. It only comes with one sheet. Still, the quality is good for the price.

Classy and timeless

Exactly what I was looking for. Not too childish, but celebratory enough for an 18th birthday. The blank interior allows for a long, heartfelt letter.

Perfect for my son's big day

The quality of the paper is exceptional. It felt very premium when I held it. The gold foil details really shine, making it a perfect keepsake for his 18th birthday.

5 FAQ

Q: Can I write a long letter on the included paper?

A: Yes, the included letter sheet is standard A5 size, providing ample space for a detailed personal message or story to accompany your greeting.

Q: What is the return policy if the card arrives damaged?

A: If your item arrives damaged, please contact us within 7 days with photos of the damage. We will offer a full replacement or refund immediately.

Q: Is this suitable for a 21st birthday as well?

A: Absolutely! While designed for the 18th coming-of-age milestone, the elegant design without specific age numbers printed on the front makes it versatile for 21st birthdays or graduations too.

Q: Does this set come with a matching sticker to seal the envelope?

A: No, this specific set includes the card, envelope, and one letter sheet, but does not include sealing stickers. You can easily purchase separate wax seals or stickers to match.

A: Our foil stamping process is high-quality and designed to last. As long as the card is stored in a dry place away from direct friction, the foil should remain intact for years as a keepsake.
