Flower tubes are a must-have for all flower projects, keeping your arrangements fresh for your florist! A favorite of butterfly rescue advocates and teachers, these easy-to-use tubes keep flowers and leafy stems fresh longer. Your 10 Essential Flower Craft Supplies: Each flower picture and hose comes with a plastic stopper with a hole to insert your flower stem. Floral hoses are the best way to keep flowers fresh until you can put them in a vase. The water tube is made of sturdy recycled plastic, while the cover is made of an easy-to-use soft rubber-like material. The lid's center opening stretches to allow single-stem floral items to be passed through it, creating a waterproof seal to prevent water leaks. Water pipes can be dropped into soil or floral foam to create a gorgeous arrangement for use in your home, special events or as a gift!
