Balls - I need some

I want some!
Just a few for some sticky polishes that need a bit of shaking.
Anyone know where I can get half a dozen without paying loads for postage, and without buying from some dodgy looking outfit in HK or similar - where I'm scared they will be made of something that weeps and ruins the polish?

When I needed some, I just got some stainless steel ball bearings off ebay - really cheap and perfect for the job (really long time ago though now so I can't remember which seller I used - I'll have a look in my history when I get a minute, see if I can track them down...). 

As I think a few people have said, anything specifically for "nails" bumps the price up loads - get something that's intended for something a bit more industrial and you're looking at a much more sensible price

The only problem is trying to work out what size to get - needs to be big enough to do the job, but not so big they won't fit down the neck of the bottle...


Edit: Looks like I used a seller called bearingstation who don't have any items for sale at the moment

My concern with just buying any old balls is - will they dissolve in the polish & change the colour? I'm sure someone had some polish where this had happened & the indie maker then switched balls (unless I dreamt this whole thing which is possible!)

I think decent quality stainless steel should be ok - when I get home, I'll check the ones I've added balls to and make sure they're still the colour they should be 

Mica Moma do giant balls which are awesome, and you only need one. I don't know how much they are though.

£1 for 10, but £3.50 postage, so not worth it unless you're getting other stuff!

Mica Moma is where I started - but they want their standard £3.50 postage for 10 balls and won't budge - even though I reckon it will cost 69p to acutally post them.
