These glass orbs are designed to float in ponds, containers or centerpiece bowls. They also look wonderful sitting on tables or in garden beds. The combination of opaque and transparent colors make these floats shine in the sun or shade. These floats are made with thicker glass so they are not easily broken. They can be left outside year round although they should be taken out of standing water before freezing. Small floats are approximately 2" in diameter. The medium floats are 4" in diameter and the large floats are 6" in diameter.
