The KitKat minis have a size of 12 x 92 x 8 millimetres which is smaller and shorter than the ‘standard’ Sevilla KitKat fingers at 20 x 145 x 8 millimetres. The size of the joint also differs: the minis have a joint of 2.5 millimetres, while the standard fingers have a joint of 3.0 millimetres. This means the minis are tighter and closer together than the standard mosaics.

The two tiles not only differ in size, but in how the surface is rounded. The standard KitKat is hollow, while the KitKat mini bubbles outward on top. This bubble amplifies the fragmented, kinetic quality of the mosaics. The effect is best seen on the minis with speckles - azure blue, light green and grey blue fingers.

The Sevilla KitKat minis are made of high quality glazed porcelain and are water and frost resistant. They look stunning on a flat wall and well suited for the tiling of curves like counters, bars and kitchen units. When the KitKat mosaics are used on a straight wall, they can be placed both horizontally and vertically. On curved surfaces they are placed vertically.
