10 yr old boy help!

[annabanana19]

My nephew and niece are coming on Saturday (usually come after Christmas which gives me time to get to the sales! ) and im stuck for ideas. Main gift will be a £10 voucher as they need new winter clothes (moving to a colder climate) but id like some small things to open.

Already have:

Magic gloves x 2 pairs
Tube of chocolate

Now I'm stuck. Need some tat type things. Just a small gift to open. Not into football but into lego which is expensive!

Lego figures or a small set (they start at round £5)
