Folio vs Shell Case Specs
Form factor design
The CoBak case is a folio design. It wraps around your Remarkable Paper Pro 11.8-inch tablet. This style includes a front cover that folds over the screen. The magnetic closure keeps the device secure. You get full front and back protection in one unit. The MINGFENG case is a shell or back cover. It fits the Onyx Boox Tab Ultra C Pro 10.3-inch tablet. This design only covers the rear and sides. You leave the screen exposed when not in use. This makes it lighter and easier to grip. You choose based on whether you prefer full coverage or minimal bulk.
Screen compatibility
Screen size compatibility is critical for a proper fit. The CoBak folio is tailored specifically for the 11.8-inch Remarkable Paper Pro Color Tablet released in 2024. It features precise cutouts for this larger display. It does not fit the older Remarkable 2 model. The MINGFENG shell is designed for the 10.3-inch Onyx Boox Tab Ultra C Pro. The size difference matters for your device. If you have the larger Remarkable, the CoBak is the correct choice. If you use the Boox, the MINGFENG shell fits perfectly. You must match the case to your specific tablet model and screen size.
Protective materials
Protection levels differ between the two materials. The CoBak folio uses a hard PC back shell and waterproof PU leather exterior. The corners are reinforced with 100% PC for durability. The interior has anti-slip material to hold the tablet securely. This combination offers robust defense against drops and scratches. The MINGFENG shell is made of silicone. It is described as lightweight and portable. Silicone provides good shock absorption but lacks the rigid hard back of the CoBak. The CoBak offers more structural protection, while the MINGFENG offers flexible, lightweight shielding.
Smart features
Smart functionality varies significantly between these cases. The CoBak folio includes an auto sleep/wake function. The magnetic folio activates your device when opened and puts it to sleep when closed. This optimizes battery life during extended standby times. The MINGFENG shell does not mention any smart features. It is a passive back cover. You will need to manually control the screen state on the Boox tablet. If you value automatic battery saving and convenience, the CoBak folio is superior. The MINGFENG shell relies on manual interaction for screen control.
Stylus storage
Both cases include holders for your stylus. The CoBak folio has a built-in pen holder and a small refill holder. It uses the pen's own adsorption to keep the marker secure. This keeps your stylus and refills accessible and safe. The MINGFENG shell also includes a pencil holder. It allows you to store the stylus while keeping the case slim. Both options solve the problem of losing your pen. The CoBak offers additional space for refills. The MINGFENG keeps the profile lower. Both provide practical storage solutions for your writing tools.
Water resistance
Water resistance is a key durability factor. The CoBak folio is explicitly described as waterproof. The exterior is made from high-quality waterproof PU leather. This protects your tablet from spills and rain. The MINGFENG shell is made of silicone. While silicone is naturally water-resistant, the product data does not claim it is waterproof. It protects against dust and minor splashes but may not offer the same level of liquid protection as the CoBak. If you often use your tablet outdoors or near liquids, the CoBak's waterproof rating provides an advantage.
Which Folio or Shell Case Suits You
Users needing full front screen coverage
You should choose the CoBak folio if you want complete protection for your Remarkable Paper Pro. The hard PC back and waterproof PU leather shield the device from drops and dust. The magnetic closure keeps the tablet secure when not in use. This design offers robust defense for your 11.8-inch screen and body.
Readers preferring minimal weight and bulk
The MINGFENG shell is ideal if you prioritize a slim profile. This soft silicone back cover adds minimal bulk to your Onyx Boox Tab Ultra. It measures just 0.47 inches in height. You get essential scratch protection without the extra weight of a full folio, keeping your 10.3-inch tablet lightweight and portable.
Buyers wanting built-in stylus storage
If you need a dedicated place for your pen, the CoBak folio includes a built-in holder. It also features a small refill holder for nibs. This keeps your stylus and accessories secure and easily accessible. The MINGFENG shell offers a pencil holder, but the CoBak provides more integrated storage solutions for your writing tools.

Frequently asked questions
Does a folio case protect the screen better than a shell?
Yes, a folio case provides superior screen protection. The CoBak Folio includes a front cover that folds over the display. This design shields the screen from scratches when the tablet is in a bag. A shell case, like the MINGFENG option, leaves the front exposed to potential contact.
Can I store my stylus in a shell case?
Some shell cases include stylus storage. The MINGFENG Silicone Shell for the 10.3-inch Boox Tab Ultra features dedicated space for a pen. This allows you to keep your stylus attached to the device. It offers minimalist protection without adding excessive bulk to your setup.
Do folio cases help save battery life?
Folio cases can aid battery conservation through auto sleep features. The CoBak Folio for the Remarkable Paper Pro supports auto sleep and wake functions. Closing the cover puts the device to sleep automatically. This prevents accidental screen touches and reduces power drain when the tablet is not in use.
Which case type is thinner and lighter?
Shell cases are generally thinner and lighter than folios. The MINGFENG Silicone Shell measures just 0.47 inches in height. It provides a slim profile for users who prioritize minimal bulk. Folio cases add more material due to the front cover and magnetic closure mechanism.
Is a shell case suitable for travel?
Shell cases offer less protection for travel. They lack a front cover to shield the screen from pressure or impacts. The MINGFENG Shell is best for desk use or careful handling. If you frequently carry your tablet in a crowded bag, a folio with a hard back is a safer choice.
Can I use my tablet with the case on?
Both case types allow full tablet functionality. The MINGFENG Shell is made of silicone and fits snugly around the device. The CoBak Folio wraps around the Remarkable Paper Pro securely. You can write and view content comfortably with either option installed, as they do not obstruct the screen or buttons.
