The vases are made of natural birch bark, wrapped over a metal container. It measures 9 tall and has a 4 3/4 opening. This would be a wonderful addition for your wedding tables or home decor! I used these as part of the centerpieces for my own wedding and people were actually asking to buy them as they left for the night! Wood burnt initials surrounded by a heart can be added. Just choose the option and PM the initials youd like.
