Fixpoints Flower-Power start number magnets

No more training clothes with holes from safety pins! Attach your start number with Fixpoint's start number magnets!

You get four magnets in one package, which are attached to each corner of the start number. A set of magnets weighs only 12 grams and can withstand a weight of 1.1 kg!

Tested in Råskinnet 2013: Futt'n Fart

NB!
For safety reasons, the magnets should not be placed near bank cards that could be demagnetized.
The magnets can be used on start numbers where the chip is attached to the back, but attach the magnets a little away from the chip. If the magnets are attached in each corner, they should not affect the chip.
Bib number magnets must not be used by those with pacemakers.
