Ph lab NUDAI Slider-YAOZAI EDITION

Push the slide plate with your thumb and a spring-loaded bead rides across internal track segments, landing each position with a detent.

The structure's defining trick sits underneath: a tool-free quick-switch reconfigures the push travel by hand, giving two distinct modes from one body with no tools and no teardown.

Sound and feel split cleanly. A short detent snap you feel under the thumb, a tight click you hear — neither loud enough to carry across a room. The bead-blasted finish keeps glare down and grip up.
Build integrity is the quiet sell. All quick-release parts leave the factory in a tight-fit state, so the bite force holds after long use rather than loosening into play.

The compact footprint carries flat, doesn't roll on a desk, and runs one-handed end to end.

It ships in two materials. Bead-blasted stainless steel runs heavier and warmer with a deeper click; the zirconium-alloy version is the lighter, sharper-sounding variant.
