Siloa’s Dual-Neck Vials allow the consumer two application systems of the same product from a single vial, allowing them to “spot, spritz, pump, drop and roll.” Three combinations are now available in varying capacities.
 
The Fragrance DNVs feature a mist pump and steel roller ball. The Treatment DNVs feature a serum pump and glass roller ball. The Oil DNVs feature a dropper and glass roller ball. Variable sizes are available.
 
Siloa says additional combinations of dispensing attributes are in the works. All versions are refillable and travel-friendly. All decoration options are available along with funnels, pouches and other accents.
