Ever one to jump on a bandwagon, Proporta has unveiled two St Patrick's Day products for Apple iPhone users and the fashionable geek.

"Handmade from the finest quality black leather" the St Patrick's Day Aluminium Lined Leather Case (iPhone 3G) features an exclusive green letterbox lining in honour of St Patrick, the Patron Saint of Ireland.

Last month Proporta released a special-edition version of its Alu-Leather Edge iPhone Case in honour of the 200th anniversary of the birth of Charles Darwin.

The iPhone case includes cut outs that allow access to all ports and controls, "elegant contrast overstitching", and, of course, the exclusive green pillar-box lining in honour of St Patrick.

Only 25 will be made, and are priced at £27.95 each.

St Patrick's Day Memory Wallet

Proporta is producing 50 limited-edition leather wallets in the same green letterbox lining, at £25.95 each. The St Patrick's Day Leather Memory Wallet features essential secure storage space for memory and phone SIM cards, as well as separate compartments for safe storage of credit cards and cash.
