Materials vary but often include heavyweight paper and card stock (for example, 270gsm uncoated stock), thick kraft paper, premium ivory cardstock, and sometimes cards are individually wrapped in PLA sleeves.
Many sets come ready-to-use: cards are individually wrapped, treat holders are provided as transparent sealed plastic bags (often with tape), and some kits include pre-cut twine, heart seals, envelopes, or peel-and-stick flaps for quick sealing.
Designs range from simple, no-accent cards to highly embellished options. Decorative features include bright printing and embossing, multicolor artwork, shaker stickers and emblem seals, and other printed or tactile accents.
Assembly ranges from minimal to moderate. Many kits are ready-to-fill or include tape/twine for quick attachment, while some box-style or detailed kits may need more time and precise folding (a few reviewers noted fiddly fold points on those kits).
Some sets include envelopes (often sturdy or colored) and may offer peel-and-stick or hand-embossed options so you can seal without licking. Other exchange kits use sealed plastic treat bags or sticker seals instead of traditional envelopes.
