DND Gel Base + Top Coat Combo includes one bottle DND Base Coat (prep layer for color adhesion) and one bottle DND Top Coat (seal layer for high-shine finish and chip resistance). Some combos add a matching color Gel & Lacquer Duo for a complete starter kit.
DND Base and Top are the foundation of the 21-day wear system. Buying as a combo saves vs separate bottles, ensures matched chemistry between base and top, and is the most-restocked SKU pair for any salon offering DND service.
One DND Base + Top combo (typically 0.5oz each) covers approximately 40-60 manicures before restock. Heavy-volume salons may go through one combo per month; smaller salons every 2-3 months. Buy 2 combos at a time to avoid stockout.
DND Base and Top are formulated to work best with DND Gel Polish for the full 21-day wear claim. They will cure with most professional gel polish lines but cross-brand compatibility may reduce wear time. Recommend matching all 3 layers for maximum performance.
DTK stocks both DND Top Coat options: No-Wipe (#600, ready to use after cure) and Wipe-Off (requires cleansing pad after cure). Most salons prefer No-Wipe for faster service. Confirm which variant is in the combo before ordering.
