These are dry and cracked.
Either need a handy man, or decor only!
I would not suggest that you use them in the water.
Even though the one is separting, it is still solid. Not going to break easily. 

I am giving UPS and FedEx as shipping options.
I live 32 miles from the nearest drop off. You need to allow up to two weeks for this to be shipped.
There are times we don't go to town for a while. 
It's not usually that long, but sometimes it is.

USPS I can ship in 1-4 days.
