A new shop from Sweden called Clas Ohlson has opened in Leeds recently, I think they have about six other branches in the UK.
They sell some interesting stuff and everything is on their website - but they don't do mail order so you need to be able to get to a shop.
I wondered if anyone has tried this item and whether it is any good for (non-medical!) DIY purposes:

also sell a Velcro-like thing called Duotec which has mushroom shaped projections on both halves rather than hooks and loops - it seems a lot stronger than standard Velcro and has to be pushed together a lot harder to make the two halves connect. It's expensive too at =A33 for a 25cm strip.
