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.)
A seven-petaled flower with deeply ridged petals sits at the bottom of this marble so that the top half acts as a magnifying glass, enlarging the bloom when viewed through the top. The flower is yellow with a red and yellow stamen.
