Thank you for looking. This is a hexagonal terrarium made of stained glass. It uses dark reddish-purple and two types of clear glass. The roof can be removed for easy insertion and removal of plants and for maintenance. Both use antique glass stained glass. It creates a very mysterious look depending on the light. This is a quite large terrarium. It looks beautiful just displayed as is, but it's also stylish when you add plants and small items. It looks like a greenhouse. Size Hexagon side: 15 cm Diagonal diameter: 30 cm Height: 26 cm Lid side: 16 cm As this is handmade, I would appreciate your understanding regarding slight variations in size and the overall finish. I will pack it carefully and securely for shipping, but in the unlikely event of significant damage, please contact me before leaving a review. I also have a shop on Mercari Shops.
