What a tropical island look for outdoors or indoors! I think they wired them together to give more stability. Coconut shells are round after all.
I’d prefer them not hooked together, but then you’d need something underneath to keep them stable. How about hot-gluing a metal ring of some sort that wouldn’t show that much? Or place the coconut shells in a bed of sand or pebbles & then wiggle the shells down into it a bit so they are held steady. That would look really nice too.
One important thing in the comments was that votive candles can get very hot on the bottom as they burn down & they could cause the coconut shell to burst into flame. Not good. One suggestion was to put a kind of wired grid under the votive to keep some separation from the shell. Another was to float these in a swimming pool or other water container. That would be beautiful, IMHO. How about filling the coconut shell with flat marbles in water colors (or other) and then set the votive directly on the glass pebbles? I think that would look very cool. Now I think I better go get some coconuts & figure out a way to use the meat of it. I hear that the coconut “milk” is very healthy for you. Hmmm . . . drink recipes?
They say you can use a pillar candle in these if you like, but be sure to make the shell stable first. For any candles, don’t leave them alone. Always keep an eye on them.
