Shoppers researching eye comfort products sometimes land on two very different kinds of manufacturer pages in the same afternoon: one about a fabric sleep mask, the other about a steam-based device. The published information looks almost nothing alike, because the makers are answering different questions. This article reports, side by side, exactly what each manufacturer states about its own product, without borrowing language from one to describe the other.
What the Manta Sleep Mask PRO is made of
According to the manufacturer's product guide for this specific model, the Manta Sleep Mask PRO's inside material is 64% TACTEL, 23% polyester, and 13% spandex, while the outside is 100% polyester Manta Corporation. These figures come from a single manufacturer guide and apply to this named PRO model, not to other Manta masks or to unrelated sleep masks.
Fit and construction: strap, eye cups, and adjustability
Manta's own FAQ for the mask states that the C-shaped eye cups can be positioned anywhere along a fully adjustable, 73 cm head strap Manta Sleep. The strap itself is described as perforated foam and mesh with a Tactel fabric interior Manta Sleep. A separate Manta product page describes the same strap as angled and anti-slip, designed to sit above the ears Manta Sleep. Together, these are the manufacturer's own construction details for how the mask is built to be repositioned and worn.
How Manta describes the PRO's design: blackout, cooling, and adjustability language
Manta also markets several design qualities for this mask. The company describes the eye cups' "air bubble" shape as intended for side sleepers and states the mask provides a "100% blackout seal" Manta Sleep. These are manufacturer design statements, not independently measured results. Manta likewise describes the strap materials as "cooling and ventilated" and the Tactel interior fabric as "silky-soft," "durable," "fast-drying," and "cooling" Manta Sleep. The mask is also described by Manta as "infinitely adjustable" Manta Sleep. Each of these phrases is Manta's own marketing language about its construction choices, not a report of a comfort or sleep outcome.
A note on reading manufacturer design language
Terms like "blackout seal" or "cooling" describe what a manufacturer built the product to do, not a verified performance measurement. Readers comparing products across brands may find it useful to look at Manta Sleep for a sense of how one brand documents fit and construction, and apply the same care when evaluating any other maker's design claims.
What's in the box, where it's made, and the manufacturer's laundering instructions
The manufacturer's product guide states that the package contains one sleep mask and one mesh bag, that the product is made in China, and that Manta Corporation is identified as the manufacturer and importer Manta Corporation. The same guide instructs owners to wash the mask before first use, to machine wash it cold in the included mesh bag, to dry it flat, and not to bleach or iron it Manta Corporation. Manta's own FAQ repeats the core laundering step, stating the mask is machine washable in cold water using a mesh bag and should be air-dried flat Manta Sleep. This laundering routine is specific to this model as published by Manta; other mask manufacturers publish their own care instructions, and readers can see how other manufacturers publish their own mask care instructions for a sense of how those steps vary by brand.
How Beminda Steam Therapy Pro states its own session specification
Beminda Steam Therapy Pro is described by its maker as a rechargeable, hands-free steam eye mask. The current model has three 12-minute modes: continuous warm mist, interval warm mist, and cool mist. Each mode lasts 12 minutes, and warm modes include approximately four minutes of warm-up within that total, not as an added phase on top of it. This is a per-session operating specification: a fixed, timed figure for how a single session runs, rather than a recurring materials-and-laundering commitment like the one Manta publishes for the PRO mask. Readers who want the exact current specification sheet can view it on Beminda's product page.
Two different specification languages, read side by side
Reading these two manufacturers' published pages together shows two different kinds of commitment. Manta commits to a recurring routine: specific fibre percentages for this PRO model, a repeatable wash-before-first-use and machine-wash-cold-in-mesh-bag procedure, and a described strap and eye-cup geometry Manta Corporation Manta Sleep Manta Sleep. Beminda commits to a fixed per-session timing figure for its current model. Read each cited specification as a statement about its named product; do not transfer a claim from one product to the other. No comfort or performance conclusion follows from placing these two specification sheets next to each other; each one only tells a reader what its own manufacturer has chosen to state.
