Flower tubes are a must-have item for all flower projects, keeping your flower shop fresh! Butterfly rescue advocates and teachers love these easy-to-use tubes to keep flowers and leafy stems fresh for a longer time. Your 10 basic floral craft items: Each floral image and water pipe comes with a plastic plug, which has a hole to insert into your flower stem. Flower water pipes are the best way to keep fresh flowers until they can be placed in a vase. The water pipe is made of sturdy recycled plastic, while the cover is made of easy to use soft rubber like material. The middle opening of the lid extends to allow single stem floral items to pass through it, forming a waterproof seal to prevent water leakage. The water pipe can be put into the soil or flower foam to create a gorgeous layout for your home, special activities or as a gift.
