well , order these from here and they come in prompt . once I open they I realize how much they smell with toxic petroleum chemical . -lrb- look in description it say that this chemical cause birth defect -rrb- so I keep they for a week to try to air they out , but they end up stink up my room so bad that I have put they out in the hallway before my roommate yell at I . so unless you have a good open space\/deck\/balcony where you want to air these thing out I strongly recommend stay away from these . I even wash they with detergent too as these be greasy . . do not help . there be other type of dumbbell that have other type of rubber coating that do not smell . I would try those , but I be so over rubber after these . Amazon have to send a truck here to pick these up . order plain iron dumbbell hopefully that should all be good .
