Nice little pouch. With a bit of time anyone can make one, but frankly I thought it'll take me longer to dig the bits i need out from boxes than it will to order one, so i did. At £5 i wouldn't offer to make one for anyone, so I thought it was worth the money.
Incredibly simple product and such god value for money. Have used this for years now and it's still going! Much cheaper than buying a pair of nike trainers with a little compartment. Have never had any problems with it, even through puddles!
