Asda's doing Hello Kitty clothing, Sainsbury has a whole range of things too.
I bought loads of their Hello Kitty easter eggs a while ago. And they all came with little extras.
My favourite was the medium sized egg that came with the mug. I love the mug, it's really cute.
My second wasn't actually an egg, but it was cute nonetheless. It was in a plastic egg about the size of my palm. It was a little Hello Kitty tin, and inside that was a small charm. There were about 6 to choose from, but i wanted the green / blue one hehe ^o^
They have these little Kinder egg style ones too~ They have little Hello Kitty figures in them. I used to buy them everytime I went to Sainsburys. I haven't been in a while, so i'm not sure whether or not they still do them. I may have to go check it out and see, because I really want to collect more! There are 24 to get, so you can see I have a long way to go haha.
I did also buy the egg cup, just so I could have a cute one for University. But It wasn't the kind of quality I was hoping for. It's very plastic. And it doesn't really hold the egg properly. Could just be me, but i don't know.
