These are indispensable for flower arrangements and foliage table centres. They also look great as decor objects when they are not in use. 
Fill the centre with water and pop your fresh flowers through the holes, holding them in place as in the rose bowl pictured.
Without the water they are useful for dry or silk flower arrangements.

The frogs are an eco favourite of mine, being vintage and reusable alternative to florists' foam. 

The medium size are approximately 8cm in diameter, the large approximately 10cm  and the extra large a whopping 12cm
