Question: How long ? Will it fit over the head?

 Answer: Please check the product description. We have added the length and a picture with a tape measure and it has the metal screw clasps like the normal neck beads do, so there is no problem fitting it over your head.

Question: Does this pendent have both the names of Lord Krishna and Sri Radha on either side

 Answer: No. Carving is on the front of the pendent only, not on the back side.
