Boulder 100+ vs Dragon Shield Nest 100

The Dragon Shield Nest 100 has more interior room than the Ultimate Guard Boulder 100+, and it's the one that community reports actually get a double-sleeved Dragon Shield Matte deck into, even if it's snug. The Boulder 100+ is rated for the same 100 double-sleeved cards on paper, but its interior measures smaller, and real-world reports have that combination not closing at all.

The numbers side by side

A gap of 1.5mm doesn't sound like much, but it's the difference between a deck that closes and one that doesn't at this size. The Boulder 100+'s 68.3mm interior is one of the smallest depths of any box rated for 100 double-sleeved cards, and reviewers at Double Sleeved UK report it struggling specifically with Dragon Shield Mattes. An MTG Salvation thread goes further, with a user saying a double-sleeved Dragon Shield deck simply "didn't fit." Some people force it shut with compression, but don't count on that.

The Nest 100 sits at 69.8mm, in Double Sleeved UK's "tight fit" tier rather than their fail tier. That makes sense: Arcane Tinmen (Dragon Shield's parent company) designed the Nest around its own sleeve line, so a Dragon Shield Matte plus Perfect Fit inner stack, which runs somewhere around 66.7 to 70mm depending on the exact combo, goes in with little room to spare rather than none. Swap in the Perfect Fit Sealable inner instead of the standard Perfect Fit and the fit gets tighter still.

Which one should you buy

If you're running Dragon Shield Mattes double-sleeved for Commander, buy the Nest 100, not the Boulder 100+. It's a tight fit, not a guaranteed one, but the digest numbers and the field reports both point the same direction: more room, and a track record of actually closing.

If your sleeve stack is thinner, an all-KMC combo of KMC Hyper Mat outers with KMC Perfect Fit inners measures around 66mm, which comfortably clears both boxes. In that case the Boulder 100+ is the better pick. It's rated for 120 single-sleeved versus the Nest's 115, it's cheaper in most markets, and the tight-fit problem only shows up with thicker sleeve combinations. There's no reason to pay more for the Nest if you're not running Dragon Shield's own sleeves.

Neither box is the roomiest option for double-sleeved 100-card decks. If you want a size that swallows any combo without thinking about millimeters, look at boxes with interior depths closer to 75-76mm instead; our double-sleeved 100-card fits page lists them.

Quick answers

Does the Dragon Shield Nest+ 100 (the version with a tray) fit differently than the regular Nest 100? No. Both measure the same 69.8mm interior depth and carry the same rated capacities. The Plus version adds a card tray, not extra depth for the deck.

Why does Ultimate Guard rate the Boulder 100+ for 100 double-sleeved cards if it doesn't actually fit Dragon Shields? The rating reflects Ultimate Guard's own sleeve line, likely a thinner combination than Dragon Shield Mattes plus a Perfect Fit inner. Manufacturer capacity ratings assume their own sleeves unless stated otherwise, which is exactly why real-world reports matter more than the number printed on the box.

Is there a box that fits 100 Dragon Shield Mattes without it being tight? Yes. Boxes with interior depths above roughly 74-76mm handle Dragon Shield Matte double-sleeve stacks comfortably. Check our how many double-sleeved cards actually fit guide for the math behind that number.

Marketing capacities are a starting point, not a promise. When two boxes both say "100+," the interior depth and the sleeve you're actually running decide which one closes.
