Flubber (Flexible Rubber) is an extremely strong base coat and builder in 1. Originally designed for use with our iLac colors to provide the ultimate in strength. Curing time: 30 seconds. When applying a thick layer, we recommend curing for 60 seconds. The removal time (soak off) is approximately 7 minutes. Ideal for building short nails because the cover and nude have a thicker consistency than the clear.
