You know how my son tends to get interested in odd things, like how he got a smoke machine for his last birthday? His latest must have item is a sushi conveyor belt. Here are some toys I found on eBay. They are quite pricey, £50 and up, so if he does want one, he'll have to wait until next October and another birthday!
I was able to buy him this set in the meantime, of little erasers.
