I've been a customer of LandOfMarbles for several years. They have a wonderful assortment of quality marbles. This order was for an 11 year old autistic boy. He was "over the moon" with excitement when he received the package. I'll keep buying.
Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
There are three varieties of this marble; all are bugs in a field of grass and flowers. There is an orange marble with a black spider, a red marble with a black and orange dragonfly and a green marble with yellow and black bee.
