  The two-flavour colour-superconducting (2SC) phase in small strangelets is
studied. In order to describe the 2SC phase we use the three-flavour
Nambu--Jona-Lasinio model. We explicitly take into account finite size effects
by making use of the approximation for the density of states in spherical
cavities called multiple reflection expansion (MRE). The thermodynamic
potential for the 2SC strangelets is derived in the mean-field approximation
with the help of the MRE. We found that 2SC phase survives in small strangelets
with a sizable gap. Consequences for the 2SC phases are also discussed.
