The moving sand art picture is a combination of fine sea sand, water and air in an enclosed glass space. When you flip the moving sand art picture , the flowing sand will form a three-dimensional beautiful landscape picture. The golden ones look like desert, blue ones look like deep sea, green ones look like forest and grassland, etc. Other beauties are waiting for you to discover. Due to the long time transportation, when you receive the package, if you find that the sand is piled up solid and not flowing, please shake it several times to let all the fine sand piled up loose, so it will flow well. If you receive the sand painting, there is broken or damaged, please contact us in time.
