  • Paper quality: Look for thick cardstock (300-400gsm) or premium gloss finishes for durability and a premium feel.
  • Enclosures and packaging: Envelopes should match the card size; some options include additional seals or protective packaging for gifting.
  • Origin and sustainability: Some cards are made in America with eco-friendly paper; consider mills and environmental impact if that matters to you.
  • Personalization space: Ensure there is enough room on the inside or back for a handwritten message that adds real meaning.
  • Professional vs. casual aesthetic: Card designs range from formal to playful; pick a style that aligns with your son’s tastes and life stage.
  • Delivery considerations: For timely gifting, verify shipping speeds and packaging protections to prevent damage in transit.
  • Value and durability: Thicker cardstock and quality printing tend to offer a longer-lasting keepsake compared to flimsy cards.
