Ultimate Guard Boulder Solid 100+ Deck Case (Red) – Holds 100 Double-Sleeved TCG Cards, Secure & Durable

The Ultimate Guard Boulder Solid 100+ is a deck case built to hold up to 100 double-sleeved or 120 single-sleeved standard-sized trading card game cards. Made in Germany from durable plastic, this red case uses a tight, secure closure to keep your cards from spilling. It is part of a modular storage system designed to fit into Ultimate Guard Arkhives, Superhives, and Omnihives, making it a practical choice for players who carry multiple decks.

Key Specifications

How does the closure work?

The Boulder uses a rigid, precisely molded lid that snaps shut with minimal tolerances. This design prevents accidental openings even when the case is jostled in a bag. The closure is engineered for repeated use without loosening over time.

Can it hold cards in sleeves from other brands?

The manufacturer states the capacity is based on Ultimate Guard sleeves. If you use sleeves from other brands, the fit may vary slightly. The case is designed to hold standard-sized cards, so most standard sleeves should work, but the number of cards that fit may differ.

What storage systems does it work with?

The Boulder Solid 100+ is sized to fit snugly into Ultimate Guard Arkhive 400+, Arkhive 800+, and compatible Superhive and Omnihive products. This allows you to organize multiple decks in a single, larger case.

Is the case see-through?

No. The Boulder Solid 100+ has no transparency, so your deck is not visible from the outside. This is a deliberate design choice for players who prefer privacy or want to obscure their deck choice.
