Qiyi 4x4 Thunderclap - 60mm version

Following on from the huge success of the 3x3 Thunderclap - well known for being an excellent quality speedcube, at a budget price. The 4x4 Thunderclap continues in the same vein. Multiple features give this cube a feeling of quality, despite the budget price:

Edge and internal piece contact surfaces feature friction reduction grooves, for faster more fluid turning.

Corneer rounding optimisation - A lesser degree of rounding on inner layers improves stabilty, whilst a higher degree of rounding oon the outer layers enhances corner cutting ability.

Dual level internal mechanism - reduces popping. Combines two locking mechanisms for an entirely new feeling.

Single piece mold construction - piece surfaces are smoother, and have greater precision.

Elarged outer layers - ALlows faster turning speed during the 3x3 stage of the solve.

The cube comes in two sizes - the standard size 62mm, and the smaller 60mm size.
