Velcro for strobes' fibre optic mask. Where from?

Hi,

Thanks to all for their help with red filters and lighting underwater -
I've bought a strobe kit on ebay, but am missing the Velcro mask thingy,
which goes on the end of the fibre optic link, and in front of the
camera flash.

Can I just get some ordinary Velcro from a haberdashers, or B & Q, or
does it need to be special underwater stuff.

If the latter, can you buy it on its' own and where from.

I could buy a new cable, which would come with the mask, but dont see
the sense in spending £35 for something I dont need.

Many Thanks
