Unlike traditional Nylon bottoms which produce a "thud," the Magmallow top (and bottom pairing) creates a porous acoustic signature. The plastic is not quite silicone, but it has a lower durometer (softer plastic) than standard ABS. This results in a bottom-out sound that is described as "marbly" or "squishy" in the best way possible—it eliminates the harsh clack. Typing Feel: The Train vs. The Marshmallow The name promises a contradiction: a heavy train and a soft marshmallow. How does that work in practice? The Press (The Train) Because this is a "Train" series switch, the stem poles are extended. This means the travel distance is shorter than a standard Cherry MX Red (4.0mm). The initial press is light—around 45g. However, due to the POM stem and polished rails, there is zero scratch . The smoothness is comparable to a well-broken-in Gateron Ink Black.

But every once in a while, a switch comes along that defies easy categorization. Enter the Nobara Train Magmallow Top . | Specification | Value | | :--- |
You are a speedrunner who needs the fastest reset possible (go with Tangerines), or you absolutely hate the feeling of bottoming out on a soft surface. This results in a bottom-out sound that is
You type all day for work and want a "pillow" at the end of every keypress, or you want a deep, non-meta sound profile for your next build video.
As you approach the bottom, the "Train" aspect kicks in. The long pole hits the bottom housing earlier. You feel a distinct "clack" of the pole hitting plastic, but instead of a painful thud, the Magmallow absorbs it. This is where the switch shines. When you bottom out a standard linear switch, your finger joints feel the shock. On the Nobara Train Magmallow Top, bottoming out feels like pressing your keycap into a soft felt pad .
