Floral tubes are a crafting essential for all flower projects and keep your arrangements florist fresh! A favorite of butterfly rescue advocates and teachers, these easy to use tubes keep flowers and leafy stems fresh much longer. Your 10 Essential Floral Crafting Supplies: Tips, Tools, and Tricks eGuide will be emailed to you upon shipment of your order. Each floral pic and water tube comes with a plastic stopper with a hole in which to insert your flower stem. Floral floral water tubes are the best way to keep flowers fresh until the flowers can be put into a vase. Water Tubes are made of sturdy recycled plastic, while the caps are made from soft, rubber-like material that is easy to work with. The middle opening in the cap stretches, allowing for a single-stem floral item to be placed through it, forming a water-tight seal to prevent water leakage. Water tubes can be placed into soil or floral foam to create gorgeous arrangements for use in your home, special event, or as a gift! Green Floral Water pics come in sizes 4″, 4.25″, 4.75″. Clear floral water tubes come in 3″ size.
