Most sets list 4 × 6 in (approximately 10 × 15 cm) cards as the standard size. One listing specifies 12.7 × 17.8 cm (5 × 7 in). Product descriptions repeatedly reference the 4 × 6 size as the common format.
Most listings specify cards printed on ~250 gsm cardstock with matching envelopes made from ~120 gsm paper. Several packs note a glossy exterior finish on the cards and a matte interior suitable for writing.
Many cards are blank inside for personalized notes or gift cards. Some die-cut or tri‑fold cards include a pre-printed “Happy Birthday” message when folded, and one listed set includes cards pre-printed with Bible verses.
Several sets feature a glossy exterior with a smooth, matte interior writing surface. The matte interior is intended to accept pens, pencils, and markers for easy writing without excessive smudging.
Pack sizes vary by listing; common quantities shown include 24, 36, 48, and 144 cards.
Most sets include matching envelopes made from ~120 gsm paper. Several listings note v‑flap envelopes or envelopes with adhesive closure options.
Some packs offer die‑cut shapes and decorative cutouts. One kids’ set is a tri‑fold die‑cut design that ships flat and folds along pre‑creased lines; most other packs are standard folded cards with printed or multicolor accents.
