Specification: each pack contains 150 green irrigation drippers for you to build a small water supply system; high-quality plastic is wear-resistant, durable, and lightweight, ensuring long-term use. Adjustable 8-hole irrigation drippers: the drippers feature 8 holes on the top, allowing you to adjust or close the water flow by rotating the black cover, catering to the varying water needs of different plants. Easy to connect: each irrigation dropper comes with a 1/4 inch barb thread connection, compatible with 4mm/7mm (inside/outside diameter) pipes; simply attach the tube to the barb to create your own small water supply system.
