Choose Stars or Hearts.Sized to drop into a small acrylic display box for more root room. Run them puddle method or add your medium — whichever you prefer. A great little corm starter.Choose your style and pack above. 10-Pack is ten loose risers; Single + Acrylic Box includes one riser in a clear display box (limited quantity).Printed to order – leave your color/finish choice in the order notes.
