THEY may not have been to many music festivals yet.

But school business students at St Helen and St Katharine School in Abingdon are hoping their innovative way of keeping your valuables safe at festivals will be snapped up by a High Street retailer.

They were showing off their wrist wallets at the Young Enterprise fair held at the Templars Square Shopping Centre, Oxford, on Saturday.

Year 12 student Annabel Record, 17, said the school business Spectrum was due to pitch the idea to a high street retailer, adding: “We know there is nothing like this on the market.”

The event was part of the Young Enterprise competition and saw 21 business teams from county schools set up to trade. Susan Ledgard-Hoile, Young Enterprise manager for Oxfordshire, said the fair came after months of planning, with students coming up with ideas for products at the start of the school year in September.

She said: “They have all worked incredibly hard and this is the first chance to test their products with the wider public rather than their friends and family.

“It is also an opportunity to see what the other schools are doing.

“It makes them feel part of a bigger picture.”

She said a mystery shopper had toured the stalls, and prizes will be awarded for categories including best customer service and best product.

The students are all year 10 or year 12 pupils aged 14 to 17.

Bloxham School pupil Tom Ward, 17, was part of a team selling tie-dye T-shirts for £9.

He said: “It’s fun, it is unisex, it is quite a broad market and they are quite popular at the moment.”

A team from Oxford Spires Academy were selling their £15 solar-powered mobile phone chargers called i-Solars.

Behraam Khan, 16, said the team came up with the idea after becoming frustrated with problems trying to charge their mobiles.

He said their charger would fully charge a phone in an hour and could be used on most mobiles.

Kashif Hussain, 17, said he had fun selling the product to shoppers, adding: “It’s amazing. We are enjoying it.”

Abingdon School pupils were selling their sustainable and easy-clean bird boxes named Home Tweet Homes.

David Mackney, 14, said it was good to see the product go on sale. He said: “We have had great interest.”
