Meet expectations.
Good product, is the exact case I was looking for to protect my most valuable cards!

Exceeded my expectations
Exactly what I was looking for. Just pop in the card and close it. It’s real easy. Flattened out my annoyingly curved Topps chrome cards easily. All the corners are well protected too. I’ll buy more as needed.

Great
These magnetic card holders are perfect for protecting and displaying trading cards. The magnets snap shut securely and hold the cards in place without damaging them, while still making it easy to open when needed. The clarity of the plastic is excellent—cards look clean and sharp inside, almost like they’re in a professional display case. Getting a 60-count pack is a great value, especially if you have a larger collection. The consistency across all holders is solid, no warping or loose magnets, and they feel durable enough to last for years. If you want an affordable, reliable way to protect your cards and keep them looking their best, these one-touch magnetic holders are a great choice. Highly recommended for collectors!

First time purchasing, maybe I got unlucky
These are pretty bad. First off, pictures are misleading. If you look at the corners, they have different shapes between the pictures. I bought these because the shape implied a perfect fit but there is a gap that allows the card to jiggle. The polarity on the magnets isn’t uniform. Sometimes I can stack these cases and sometimes they repel each other. Tons of little white hairs inside each sealed case. Magnets broken on some cases, scuffs and weird dirty marks inside the literal glass. I can’t rub them off. Not sure if I just got a terrible batch or what but this feels like a rip off. Maybe 40ish usable cases out of 60

Magnets bad sometimes
Some are trash because of the magnets. But for the price, it's a deal!

Product arrived as shown comparable to magnetic holders purchased at Walmart. Significantly cheaper but slightly lower quality, good buy.

These holders are way better than anything we had in the 90s! Easy to use and the magnet holds strong.

Holders came damaged. The tops of the holders are also frosted. The images show they are transparent. The edges are not smooth to the touch and feel sharp. Overall feels very low quality. I recommend looking elsewhere.
