Shipping Notes

Buying more than one item?

Royal Mail’s system is complex, so most sellers charge a flat rate or give ‘free shipping’. Either way, when you have a larger order, you pay the same to ship per item as if they were all sent singly - like on Amazon.

Instead, we charge £1 for packing, plus actual postage, plus tax. If you buy several items, the website can’t always calculate the true postage, but we will refund excess post over £1. Other sellers don’t do this.

Total P&P charged is listed when you move to PayPal to pay.  If this is more than the actual cost, we’ll promptly refund the extra.

We use Royal Mail at cost:
UK: First Class, plus Signed For (orders over £35).
OUTSIDE the UK: Airmail, with Tracking if available, Signed For if not.

More About the Duet


Made of a non-allergenic, nickel-free stainless steel, the Bioflow Duet’s elegant yet durable design will complement almost any style of dress, for men or women.  People who suffer from metal allergies are unlikely to experience problems as the steel is nickel-free.   Each ball-end on the torc holds a half-power CRP unit, spreading the therapeutic load across the blood vessels of your inner wrist better than the basic system.  For details of how the CRP system works, go to our Science and Theory section.


The Duet is available for three wrist sizes:

        SMALL:  130–155 mm (about 51/8  – 61/8 in)

MEDIUM:  150–190 mm (about 6 – 7½ in)

     LARGE:  180–215 mm (about 71/8 – 8½ in)

Please note that the Small size fits only children and ladies with VERY small-boned wrists.


The Duet is intended to be worn permanently.  If you’ll need to remove it frequently, a model with a clasp fastening would be better, unless you’re one of those whose wrist shape allows a correctly-fitted Lux to be easily slipped on and off without reshaping the band.
For suggested clasp and buckle models, see the Elite, the Executive and the Explorer 2. You might also like the Pirouette, which is an all-metal bracelet in polished steel or gold plate.

Your Duet should be worn slightly loose, so as to be able to slide up and down your arm a little, but it should not twist right round – the Bioflow CRP modules should be free just to move around over the pulse area on the inside of your wrist and lower arm.  It’s essential to wear your Duet with the CRP modules on the inside of your wrist where there are most blood vessels.  Otherwise its therapeutic effect will be considerably compromised.

Magnetism Warnings

The magnetic modules on the Duet are pretty powerful! That’s one reason why the Bioflow system works, when other magnetic products generally don’t.  This strong magnetic flux is, because of the patented design, almost entirely turned into your wrist when you are wearing the bracelet.  Take note, then, that when it is off your wrist, touching vulnerable objects may cause unwanted effects.  This includes temporarily stopping watches, wiping the data off magnetic stripe cards, and so on.  Leaving the Duet on, for example, a bedside table with a watch, entangled inappropriately, may stop the watch until you separate them.

If you have a heart pacemaker or similar device, the back (outer) side of the CRP magnetic units will cause no problems unless the pacemaker is over 20 years old (some early types were un-guarded).  Even so, it’s best to check with your cardiologist before using any Bioflow; and of course, somehow managing to turn a Duet inner magnet face into just the wrong spot on your chest might reset an old pacemaker anyway - though this could hardly happen accidentally!

Cleaning and Maintenance

Wash your Bioflow Duet with ordinary detergents; this is probably easiest as you wash your hands.  Both the stainless steel and the resin cover over the CRP modules are water-resistant in ordinary conditions of use.  Bioflow Ltd (because of unreasonable claims) will not guarantee the Duet to be waterproof and recommend that you dry it after any wetting.  However, we almost never see magnets fail except when the ball ends are damaged by force, breaking the waterproofing.

Like any other metals you wear, the steel can be scratched by fine or coarse grit.  So avoid, for example, rubbing the wristband unprotected on a table, to prolong the bright finish.  The gold plating is an alloy, harder than the pure gold in electroplate, so it will resist scratching better.  Nevertheless, it is still softer than steel, so will need more care to keep the finish bright.  As you’d expect, scratching, gouges and plating wear are not points covered under the 12-month fitness-for-use guarantee; but with care, the finish will look good for many years.  

The Duet in Sports and Industry

Sports users find the Duet a good design because it’s very light and doesn’t cause problems when it gets sweaty.  For games like tennis, you might prefer to slip a terry-cloth wrist guard (sweatband) over it during play to collect the moisture.

When worn in an industrial setting, flying particles like non-ferrous swarf, sawdust and blast-cleaning dirt will be no problem - if you get an irritation just dunk your wrist in water and rinse.  Ferrous swarf and steel particles (for example, in sump oil) can be a problem if allowed near the Duet bracelet.  They will collect around the CRP unit and will need wiping off periodically with a rag, which can then be shaken out.  Better would be to wear gloves if you can, or wrap a strip of cloth around your wrist under the Duet.

Putting on and Removing your Duet Magnetic Wristband

When putting on a Duet for the first time, shape the band to your wrist.  Care should be taken not to use the ball-end modules for leverage as this is done, as excess pressure can cause them to snap off - and considerable pressure IS needed to shape the band.  Be warned, and handle the band only, not the modules!

First, the back of the band should be flattened if your wrist has a flattish rather than well-rounded back.  The whole band should then be opened up enough to slip comfortably over your wrist with the CRP magnetic modules on the inside of your wrist, then closed as tightly as possible, by bending each side in turn, keeping the back as you left it.  Few people can do this unaided.  On being released, the Duet will spring open a little and this should give the perfect shape and fit.  

To remove the Duet, people with a concave inside wrist can move one module to this place then arch the Duet off the wrist.  Other people will need a friend to pull open the band from both sides, while avoiding pulling on the modules.

We recommend that you only remove your Duet on special occasions, such as where a clear wrist is essential, or when undergoing an MRI scan. It is intended to be worn permanently, to avoid ‘work hardening’ damage by frequently bending the steel band, and to minimize the small risk of breaking off a module.  As its use is a medical need, security personnel should respect this and scan you manually at, for example, airports.
