Cardstock ranges from durable kraft paper to heavyweight uncoated stock printed at about 270 gsm. Envelopes are often heavyweight (around 95 lb) embossed paper.
Most illustrated greeting cards are described as uncoated and blank inside, ready for handwritten messages.
Certifications and eco notes include FSC and SFI certified paper, TUV Austria certified‑compostable PLA sleeves that meet ASTM D6400 and EN 13432 standards, and manufacturing at regional mills that use a portion of on‑site sustainable energy.
Decorative finishes mentioned include textured surfaces, brightly printed artwork, embossing, and uncoated card stock designed for handwriting.
Each flashcard shows a bird portrait on one side and, on the flip side, lists identification details such as common and Latin names, size/weight/wingspan, a brief description, voice, habitat, and a full‑color range map; the deck also includes a checklist card.
