Giving it
Will they actually use it?
Gifts that need setting up tend to end up in a drawer. This one is meant to be simple from the first evening.
- One button to start — a second one changes the mode
- Ends on its own — after 20 minutes, no timer to set
- Stays in place — the thumb loop holds it while they read, watch or sip coffee
- Nothing to download — no app, no account
In the box: the wrap, a USB charging cable, the instruction manual and the black magnetic gift box. A USB wall adapter isn’t included.

A routine guide, included
Hands at Work, a 10-page PDF on fitting the 20 minutes into your day, comes with every order.
Not a brace. Not a heating pad. Here is what it is.
A brace is designed to support or limit movement. A heating pad is designed to warm. TheraCuff is a light device: a wrap with 48 red (660 nm) and near-infrared (850 nm) LEDs on the inside that switches itself off after 20 minutes. They do different jobs.
| This wrap | A wrist brace | A heating pad | |
|---|---|---|---|
| What it's for | LED light on the hand and wrist | Support or limit movement | Warmth |
| Power | Rechargeable battery, USB-C | None | Mains or battery |
| Session | Auto-off after 20 minutes | Worn as advised | Varies by product |
| Worth knowing | Not a brace or heating pad | Keep following your clinician's advice | Follow the maker's safety instructions |

A 20-minute routine that doesn’t ask you to stop.

Simple to use

Step 1: Slip it on
Thumb through the loop, LED side to skin. Wrap and press flat.

Step 2: Press
Button 1 sets the level. Button 2 changes the mode.

Step 3: Sit back
Read, rest or work. Off after 20 minutes.
Read the included instructions before first use.

What to expect
What a session looks like.
We can't tell you how 20 minutes will feel, because your hands aren't ours. Here's what you'll see.
- It lights up
Button ring glows blue, green or red for the level. A red glow shows at the band's edges in a dim room.
- Some LEDs look faint
850 nm near-infrared is hard to see. That's normal.
- 20 minutes, then off
Charge by USB-C when the battery light shows red.
Why it's easy to live with
Small details, so it's easy to keep up.

Cordless
Built-in battery, so it goes wherever you sit down: couch, desk, break room or car.

20-minute auto-off
Press once and forget the clock. Every session ends on its own; hold 3 seconds to stop early.

Elastic thumb loop
Keeps the band from twisting, so you can read, scroll or sip coffee while it runs.

Two buttons, no app
Nothing to download or pair, so it's as easy on day 60 as on day one.
