It would be a little small for a large island. Mine fits in the bottom shelf of my 16 inch wide coffee table. Two may be nice, or one with some candles beside it. It’s a beautiful product and seems well made.
It makes a nice centerpiece for a small to medium sized kitchen or dining room table
Not very heavy- fine for indoors but if very windy on your balcony it could be knocked over. If on a table with alittle protection on balcony it might be fine. It’s very pretty.
Yes, the flowers are made of plastic.
