The Ultimate Guard Twin Flip’n’Tray 266+ Xenoskin Petrol is an extra‑large premium deck box created for players who want maximum capacity and stylish protection for oversized Commander / EDH decks. As part of the 2022 Exclusive series, this twin flipntray 266+ xenoskin petrol model offers space for up to 266 double‑sleeved or 315+ single‑sleeved standard‑size cards in Ultimate Guard sleeves, giving room for fully loaded 100‑card decks with tokens, extra cards or even multiple decks in a single case.

The internal layout follows the familiar Twin Flip’n’Tray design, scaled up for higher capacity. Two large removable trays, each lined with soft microfiber, provide independent access to your decks and keep sleeves and foils protected from friction. A third accessory tray offers organized storage for dice, counters, tokens and other small items, turning this twin deck and dice tray configuration into a complete tournament and game‑night solution. All three trays slide smoothly and can be removed entirely for easier table use or deck swapping.

On the outside, the deck box uses Ultimate Guard’s resistant Xenoskin material, a textured synthetic surface that improves grip while standing up to everyday wear, scratches and transport. Strong magnetic closures secure each lid so the box stays firmly shut, even when filled with 266 double‑sleeved cards and heavy dice, making this 266 double sleeved card case reliable in backpacks and travel bags. The monocolor petrol blue‑green finish delivers a modern, understated look that pairs nicely with many playmats and accessories and is distinctive compared to classic black deck boxes.
