which are paint or ink-based designs that are put on as one unit and removed by means of water, alcohol, soap, or another mild solvent. More elaborate temporary tattoos may be made using stencils and airbrush equipment. In the military It is common in armies all over the world for soldiers in combat to paint their faces and other exposed body parts (hands, for example) in natural colors such as green, tan, and loam for camouflage purposes. In various South American armies, it is a tradition to use face paint on parade in respect to the indigenous tribes.

Each metallic tattoo is protected by a transparent protective film.

Aside the risk of contact allergy, wearing latex for a prolonged period may cause heat stroke by inhibiting perspiration and care should be taken to avoid the painful removal of hair when the latex is pulled off. The same precautions that apply to cosmetics should be observed. If the skin shows any sign of allergy from a paint, its use should immediately be ceased. Moreover, it should not be applied to damaged, inflamed or sensitive skin. If possible, a test for allergic reaction should be performed before use. Special care should be paid to the list of ingredients, as
