FREE GIFT - GLIDER - 1

V. Ryan 2007-2017

 

A small free gift is to be supplied with a DVD / CD storage unit. This is aimed at attracting teenagers or younger customers. An example is seen below. There are two types. One is made from polystyrene with a plastic propeller. The second is made from balsa wood and also has a plastic propeller.

 

Balsa wood is a model makers material. It is light and easy to cut and shape. It can also to painted. This makes it ideal for making model aeroplanes. A model made from this material is reasonably priced and works well.

Polystyrene is also a suitable material. It is light but it is not particularly strong and will break very easily. It cannot be painted as easily as balsa wood. A model made from this material is very cheap and works well.
