The madreporite is the "valve" for the Black Urchin's water vascular system.
• Soft Rubber Tubing || Stainless Steel Links || Magnetic Barrel Clasp
• Length: 7-1/8"
The BLACK URCHIN collection is made from loads of soft rubber tubing salvaged from my favorite San Francisco recycling center. I have been known to bring an empty suitcase in anticipation of all the cool stuff I find there.
