Question about Savic wheels

[IndigoElectron]

I bought a Savic wheel on EBay and it arrived yesterday - the seller described it as a Jumbo Large Rolly Polly 8" diameter, but when it arrived the packet said it was a Large Rolly 18cm (which I measured as 7").

It is big enough for my new hamster but I was trying to find out what different wheels Savic sell and didn't have much luck browsing the net - I read somewhere that the Jumbo and Large are the same thing, but I've also heard people on here describe the Jumbo as 8" and mine is definitely 7". Are the Jumbo and Large different sizes? And is a Rolly wheel the same as a Rolly Polly wheel?

Thanks!

It should be in a Savic pack and called a Savic Jumbo Roly Rat wheel. Can't find one to measure at the moment for you but they are not called Rolly Polly in Pets @ Home. You can get them there for about 4.99 and stand is 99p.

Thanks It's definitely a Savic Rolly but it's 18cm, I was just wondering if they did them in 2 sizes, 7 inch and 8 inch.
