Prism is Winmau's moulded flight construction, and it solves the problem every folded flight eventually has — the aerofoil is formed into the material rather than held open by a crease, so there is no fold to soften with use.

Three gauges cover the range. Alpha is the lightest and suits most players, Delta sits in the middle, and Zeta is the heaviest for maximum durability at the cost of a little weight at the tail.

The range runs across player designs from Michael van Gerwen, Simon Whitlock, Joe Cullen and Daryl Gurney, alongside plain and patterned versions on the same construction.
