Swivel Thumb Page Holder Spiral Galaxy

Hook your thumb through the ring and read with one hand. The ring turns in a ball socket, so it goes where your hand goes.

It starts as a spiral galaxy.

Four arms of colour wheel out from a bright core, with 40 white stars scattered along them.

Then it fits in your hand.

The galaxy sits flush in a black four-pointed star, 4.2 × 2.1 × 0.4 in. Its bright core is the ring your thumb goes through.

The ring is a ball.

Its outside is a band cut from a 1.15 in sphere, seated in a matching round socket. The socket's lips are narrower than the ball, so the ring stays in.

Your thumb is the only motor.

Nothing on it is powered. Turn your hand and the ring spins all the way round in its seat while the wings stay flat.

It tilts whichever way you lean.

A ball has no single hinge. The ring rocks forward, back and sideways, so the holder follows the book instead of your wrist.

Thumb in, both pages down.

The wings press the two pages open at the gutter. Your thumb holds the ring still while the book is free to lean.

Up close

It measures 4.2 × 2.1 × 0.4 in and weighs 0.4 oz, light enough that you stop noticing it after a chapter and small enough to ride in a bag with the book.

Why it swivels.

Most thumb holders have a fixed ring, so the book has to sit at whatever angle your thumb points. Here the ring is a ball band in a round seat. Spin it, rock it, or both at once: it stays seated because the seat closes in above and below the ball's widest point.

Cut through the middle, to scale. The seat is 30.0 mm round, a 0.4 mm running gap around the ball.

Good to know

Will it fit my thumb?

The hole through the ring is 0.83 in (21.1 mm) across, measured on the ridges that line it.

Can the ring come out?

No. The ring's outside is a 29.2 mm ball and the lips of its seat are 28.2 mm across, narrower than the ball, so it is held from both faces.

Does it need batteries?

No. Nothing on it is powered. The ring moves only when your thumb moves it.
