Have you ever thought of using the large sail area of a kite for advertising space? A custom kite has many uses and is both quick and easy to achieve and not overtly expensive.

At Ozone we have our own dynamic factory in Vietnam and can easily slot a custom kite into the production line. We can customize an existing and tested design of kite to your colour or logo specifications. Just choose the style of kite from our range that you would like to use, find out what colours you can have by looking at the standard options and then think about where you would like to place your design or company logo. Then send in your design and the images to your local distributor http://www.flyozone.com/kitesurf/en/contact/distributors/  and let us get back to you with a quote. If you like the quote then we will go ahead with the manufacture and normally within 2-3 weeks you will have the kite in your hands.

Here is an example from a fantastic natural refresher drink called Dwarf8, http://www.dwarf8.com/  from Switzerland but based in the kite mecca of Europe, Tarifa, where best to have a custom kite? They ordered some Sport II’s in all white sail with the logo printed on. We have made many differnet logos for our customers over the years, in particular the tube kites really stand out as we cut the logo into the sail so it shines through beautifully
