Collection of gifts for 12 year old boys and girls and upwards. We love the 4M range of science kits which proved a draw to our children (ages 12 and 14 years) at a recent show, particularly the Illusion Science and Glow Crystal Growing. Slime kits and scented stationery are very popular with children at secondary school and the sentosphere range of make your own soap and make your own perfume are ideal presents for older girls.
