I have several of these--in both the small and large sizes--arranged together on my patio, on stands of varying heights, so as to resemble pagodas on a hillside. With battery tealights in them--refer to next paragraph--the pagodas look lovely both day and night. The resin material looks very much like stone. 

I use timer-enabled, battery tealights in them. The top part of the pagoda simply sits on the main part and is, therefore, easily removable. I would not be comfortable using real candles, for fear that the resin material might melt.

Pros: Lightweight material looks like stone; battery tealights (not included) work perfectly with them
Cons: Note: As with most items, refer to measurements (not photos) for realistic expectations
