A close-fitting inner layer with an explicit maximum card size
I would choose these to add a conventional inner layer to a standard-size deck, particularly when following a Gamegenic storage setup. The role is additional coverage inside a playing sleeve; it is not a substitute for a rigid holder.
Choose it if
You need clear inners for cards within the listed size.
Look elsewhere if
You need a playing sleeve with an opaque back or a flap closure.
The buying facts
| Pack contents | 100 clear inner sleeves |
|---|---|
| Sleeve dimensions | 64 × 89 mm |
| Supported card size | Up to 63 × 88 mm |
| Material | Polypropylene |
| Role | Inner sleeve for double-sleeving |
Will it fit?
Manufacturer-statedThe maker lists 64 × 89 mm sleeves for cards up to 63 × 88 mm. A millimeter of nominal difference does not describe usable insertion clearance after seams and material are considered.
Keep the measurement labels
A common buying mistake is treating the inner-sleeve dimensions as the maximum supported card dimensions. Here the manufacturer supplies both, so use the smaller card-size figure when checking the intended card.
I would avoid extrapolating from those two numbers to claim a tested fit in a different brand’s regular sleeve. Assemble a sample before committing to the whole deck.
Count the complete setup
A 100-count pack supplies one inner per card for a 100-card deck. Playing sleeves are a separate purchase. If an existing deck box was selected around single-sleeved cards, recheck capacity after adding the new layer.
What to compare it with
KMC Perfect Fit — Standard Topload
Compare another top-loading standard inner with documented sleeve measurements.
Dragon Shield Sealable Perfect Fit — Clear Standard
Choose this only if the tuck-in closure is worth the additional deck thickness.
