Viper Defender I, II, & III Dartboard Surrounds 

Hello, thanks for asking, the Guardian Surround is a one-piece surround that is similar in size to the Defender I. The foam it is made out of is also thicker and more durable, which means it will last longer.

Hi James, the Viper Razorback is WDF accredited, as well as the Viper Slash dartboard. WDF accreditation means the World Darts Federation thoroughly examined the dartboards and they passed each category of inspection. You can read more about that here: gldproducts.com/pages/wdf-accredited-dartboards We use high quality sisal for the Razorback and Slash dartboards. They have great self-healing abilities. These two dartboards work very well for experienced players. They are two top-of-the-line dartboards.

Each one is made out of EVA foam so it would not be hard to cut it to a specific shape.

These are made out of EVA V-Foam. We have also released a series of Cork Defenders that are the same sizes, these are also made out of the V-Foam but they have a layer of real cork as well. All of those are available here: gldproducts.com/collections/all-viper-defender-dartboard-surrounds
