A side-entry inner for readers who care about the loading direction
I would choose Perfect Side-in specifically for its opening orientation. It changes the handling of the inner layer; it is not the same product as top-loading Perfect Fit with a new name.
Choose it if
You prefer loading the inner from the side.
Look elsewhere if
You want a tuck-in closure or a top-loading inner.
The buying facts
| Pack contents | 100 clear inner sleeves |
|---|---|
| Sleeve dimensions | 64 × 89 mm |
| Stated thickness | 0.05 mm |
| Opening | Side-loading |
| Maker-stated pairing | KMC Standard sleeves |
Will it fit?
Manufacturer-statedKMC lists a 64 × 89 mm sleeve and compatibility with its Standard sleeves. The side opening does not establish a sealed enclosure or a waterproof assembly.
Choose the opening deliberately
With a side-loading inner, the card enters across its short dimension rather than down from the top. I would use that difference to guide a small trial of the sleeving process, especially if an existing top-loading inner shifts during assembly.
The tradeoff is a different opening position. Do not infer that an open side is sealed merely because a regular outer sleeve surrounds it. The exact overlap and insertion process still matter.
Keep the versions separate
The verified pack contains 100 sleeves at a stated 0.05 mm thickness. Perfect Hard is thicker and uses a different pack count, while Perfect Black has a colored back. None is interchangeable solely because all appear in KMC’s Perfect range.
For a 100-card deck, one Side-in pack supplies the inners and a separate 100 playing sleeves supplies the outer playing layer.
What to compare it with
KMC Perfect Fit — Standard Topload
Choose top entry if that is the insertion method you prefer.
Dragon Shield Sealable Perfect Fit — Clear Standard
Compare when a closing flap is more important than side loading.
