How to Install the Sleeves
Installing these sleeves is straightforward, but a careful approach helps avoid creases or misalignment.
- Prepare your workspace: Lay the sleeve flat on a clean, dry surface. Hold the card by its edges to avoid fingerprints.
- Slide the card into the sleeve: Gently insert the card top-first into the open end of the sleeve. Push until the card reaches the bottom corner, then smooth out any air bubbles.
- Check the fit: The sleeve should cover the card fully without excess overhang. If the card is loose or too tight, double-check the card dimensions against the sleeve's specified size.
- Repeat for all cards: Work through your deck one card at a time. The supplied evidence does not specify a maximum stack height or recommend using a sleeve inserter tool, so manual installation is fine.
What to Know Before You Buy
These sleeves are labeled for 7 Wonders, but the evidence also lists Queen's Necklace and Small World: Tales & Legend as compatible. The pack contains 80 sleeves, which is more than enough for most games with American-size cards. The sleeves are clear, so card artwork remains visible, and the archival-safe material means no PVC or acid that could yellow cards over time.
One limitation: the supplied evidence does not confirm whether these sleeves are suitable for double-sleeving (placing a card inside two sleeves) or for use with card dividers. If you plan to double-sleeve, you may need to test with one card first. Also, the evidence does not mention a specific thickness in millimeters, only that they are 125% thicker than standard sleeves. This is a relative claim, so actual thickness may vary compared to other brands.
Overall, for 7 Wonders owners looking for a reliable, protective sleeve from a trusted brand, the Mayday Premium UltraFit sleeves are a straightforward choice backed by clear sizing and material facts.
