Let’s take a closer look at each type!
I use the same photo-cards for all the cases, so that it’s easier to see the difference.
Photo-cards are sleeved before being placed into the hard card cases.

The sleeves I used are clear photo packs (58mm x 90mm) from Daiso(100yen store).
B8 HARD TYPE CARD CASE (contains 4 pieces)
Let’s start with the most normal type.
It’s been on sale for quite some time.


If you look at the hard case alone, it has a blue tint, but once you put your photo-card inside, it’s not noticeable. It’s easy to take cards in and out because it’s inserted sideways!

Number of sheets | 4 pieces |
B8 UV 80% CUT CARD CASE HARD TYPE (contains 3 pieces)
Next up is a hard case with UV protection!
This has 3 pieces.


I thought this blue tone would be a little strong, but when I put photo-cards inside, it was almost the same as the “B8 HARD TYPE CARD CASE 4 pieces” that we saw before.
This product contains only 3 cards, but if you plan to take photo-cards outside or display them in your room, this UV protection one may be a better choice!

B8 HARD TYPE CARD CASE (Vertical) (contains 4 pieces)
Next one is a vertical type.


This is the vertical version of the “B8 HARD TYPE CARD CASE 4 pieces” that I introduced first, and it has the same look and hardness.
This one also has a blue tint, but again, once you put your photo-cards inside it’s not noticeable!

HARD TYPE CARD SLEEVES L-Size 10P


These are sleeves that I found in the fan activities section.
It said this was a hard type, so I bought them for comparison.
The part for inserting the photo-cards is designed with a slight offset, making it easier to insert and remove them!
In terms of hardness, it is softer than a hard card case, and is stiff enough that you can easily bend it with one hand.It’s sturdier than a regular sleeve, but it’s no substitute for a hard case.
Also, it feels a little too large to use as a sleeve for K-POP photocards or Polaroid (54mm x 86mm).
I think it’s the perfect size for sleeves for regular-sized trading cards (63mm x 88mm) such as Pokemon cards.
Name of product | HARD TYPE CARD SLEEVES LSize 10P |
Size | Approx. 69 x 94 mm (external dimensions) Approx 63 x 89 mm (compatible card size) |
Number of sheets | 10 pieces |
B8 High transparency HARD TYPE CARD CASE (Vertical) 3 pieces


This is the highly transparent type that I found in the store and was looking forward to!
There are protective stickers on both sides so there are no scratches from before use.
There is absolutely no blue tinge when viewed with the naked eye, and it is totally transparent, and even when you put photocards in it, the color doesn’t change.
It’s pretty good!

B8 HARD TYPE HOLOGRAPHIC CARD CASE 3 pieces


They also had hard cases with holograms on them!
There were two types of hologram patterns, and the one I bought this time was probably crystal.
It’s really sparkly!
This card also has almost the same blue color and hardness as the “B8 HARD TYPE CARD CASE 4 pieces“.
Also, this hard case has holographic processing on only one side, so the look changes when you turn it over.

I used the side without the hologram.
This makes it easier to see your favorite characters and idols, which is cute!
