Spark more play with the Design & Drill Bolt It Bucket Set! Busy builders use a real, working, power drill to attach colorful bolts to the lid of the sturdy building bucket, developing fine motor skills, STEM skills, and creativity as they play. Kids can follow the included patterns or create their own custom works of art over and over again. When they're done, flip the lid and pack the drill and bolts into the bucket for building fun on the run and easy storage.
