Cold wax also known as strip wax is effective on larger areas of the body. Use with wax warmer & waxing strips.

More cost effective as body rollers:-

1.Wax in a tin can be pre-heated to a higher or lower temperature,  than wax in cartridge. The wax keeps its density, it’s easy to pick it up with a spatula, and the wax layer is much thinner.
2. Wax is being spread onto the skin in a thin layer, grab all the hairs even very short ones because of the spatula’s pressure.
3. Comparing to the application with the roller from the cartridge one can apply less pressure onto skin with spatula thus more comfortable for client.
4. Using tin wax, save money as one uses less wax and don't have to discard any "leftovers"
