Perfect for a Lego fan, which my daughter is. However the bottom unscrews so you can wash it. Thought that was great at first. But it comes unscrewed really easy and on 2 occasions juice has been all over the bag! So naturally I did the bottom tighter well then you can't get it off as it gets stuck. Probably because of the water making it tight etc. I wouldn't recommended but only for this reason. The positives were it's a good size. Looks good and was good for my daughter of 7. The screw head is easy to get off and it has no spout it's a open cup so maybe only good for slightly older children.
I bought this is early December as a stocking filler for my partner for use whilst travelling to work. It leaks! By the time he went to use it in Jan and we discovered that it leaks, the 30 days was up and I now cant return this. It's not fit for purpose and a waste of money. I really wouldn't recommend buying this.
