Pastel Dusk Lavender latex balloons one of the latest tone sets from Sempertex. Use these to create stacks, collars, arches or to add finishing touches to your design! Goes really well with satin / matte foils. Sempertex Balloons are made from pure, natural rubber latex. No fillers, extenders, plasticisers or any cost-reducing agents are used. These balloons have excellent helium and air retention due to a high-tech and sophisticated molecular cross-link, which creates a high quality barrier, reducing gas permeability. Low burst levels are achieved by great elasticity of the rubber film. Long Helium Flotation or Air Inflation = Long Lasting Décor.
