Customer Ratings & Reviews

I loved opening these things! Lots of good hits too! Just wish the supply didn’t dry up so fast! Recently got these with some bowman value boxes. Definitely a super fun combo to rip!

This set replaces the Opening Day series and I like this way more than that set. The mascot cards are great and I pulled some really good parallels, including a numbered mascot auto!! I hope Topps continues to bring this back every season.

Great product year after year..topps is always top shelf

These is a must buy, the cards and inserts are very nice , the card quality is great , the insert variety is crazy, I will definitely purchase another box I highly recommend it to everyone

I grabbed the 2026 Topps Series 1 Baseball Celebration Mega Box from Best Buy and came away really impressed. If you’re a fan of flagship Topps products, this one delivers exactly what you’re hoping for—with a little extra excitement mixed in. The Celebration Mega Box adds a nice twist to the standard Series 1 release. You still get that classic Topps look and feel, but with exclusive inserts and parallels that make it feel like more than just another retail box. What I liked most: Strong rookie class – plenty of chances to pull key rookie cards that actually have value. Clean, classic design – Topps keeps it simple, and it works. Cards look great for collecting or grading. Exclusive Celebration content – the added parallels and inserts give this box its own identity. Good overall value – lots of packs to open, making it a really enjoyable rip session. I didn’t hit a massive card, but I still pulled a handful of rookies and shiny parallels that made it worthwhile. This is the kind of box that’s just fun to open, whether you’re a collector, set builder, or someone looking for cards to flip. If you enjoy Topps flagship and want a retail box that offers both nostalgia and upside, this Celebration Mega Box is an easy recommendation. I’ll definitely be picking up another one.

These were on of the most fun rips I’ve done in a while, you get a ton of inserts and parallels. Fun to do with kids. Highly recommend.

This was a great product for fun. Definitely enjoy some of the cars, especially the mascot.

Always a fun rip. The celebration mega's add even more hits. Parallels, mascots etc.

Such a fun set by Topps to open with my young baseball fan. My son loved all the mascot cards and the colorful 8 bit ballers inserts in almost every pack. We pulled an Aaron Judge and Derek Jeter 8 bit ballers and an Aaron Judge game day drip. Would highly recommend for any baseball fan, but especially those multi-generational rips!

Great box for the value. Worth adding to the collection if you like baseball with fun cards.

This is a fun rip of a box especially if you have kids. You get the classic series 1 stuff with a bunch of fun extras with the mascots and stuff.

The Celebration Mega Box is not only a good value, but a chance to pull fun cards.

You get some unique cards & price is not to crazy compared to other places that sell retail totally recommended

The celebration boxes are super fun and I pulled a great Shohei Ohtani card!!

Good fun rip. Just make sure its listed at MSRP. They allow scalpers to list on their site

Fun box to open with the kids. Alot of inserts and a couple numbered cards. My skn loves the Mascot cards.

Great quality cards! Nice parallels and decent rip! Great price point as well.

Great box with lots of inserts. Exclusive mascot inserts. Fun box to rip, lots of packs.

Fun cards, fun mascots, fun baseball. Still looking for my beloved Dinger.

Great selection of cards for anyone that is collecting today’s baseball cards
