From the Play website.

We present to the world of fire shows an entire, brand new line of professional equipment that stands out at first sight for the quality of the materials used, the attention dedicated to details and a truly powerful and original look.

Our research focused first of all on creating the perfect grip for every type of manipulation. We wanted it to be the most comfortable and resistant grip ever used on fire equipment. The result is what we have called X-GRIP, a tubular heat-shrink rubber that is practically indestructible, resistant to high temperatures and, unlike silicone, can also accidentally come into contact with any type of fuel without losing its fantastic grip. To make the grip truly comfortable, we apply under the X-GRIP a 2 mm thick EPDM expanded rubber sheet that is firmly glued to the T6 aluminum tubes.

This guarantees excellent heat insulation and the right softness to cushion the hardest blows.

All the equipment in the PLAY FIRE LINE is reinforced by an internal core made of the same material used for our very famous PX3 technology. To prevent heat transmission along the aluminum tube and to give the right weight distribution at the ends, we screw wooden bars underneath the KEVLAR® strips.

Finally our 100% PURE KEVLAR® strips guarantee long flame duration and the possibility of being lit hundreds and hundreds of times!
