This box includes 1 liter of eco-friendly bubble solution and 2 re-fillable aluminum bottles, each of which is pre-filled and includes a wand. The bubble wands offer a wonderful assortment of sizes for fun variety with every dip. The bottles are made of high-quality aluminum that can be refilled, reused, and recycled. Each bottle has space to write a name so there are no bubble arguments! The bubble solution is non-toxic and all components are made in California. The aluminum bubble bottles are custom designed to ergonomically fit into a child’s hand and the proprietary soft coated texture makes for a non-slip grip.
