【Higher Density Screen in Larger Size】The new size is larger at 4*4 inches in diameter, more suitable for larger pots. High pixel density is dense enough to effectively filter water from the soil without soil loss. Each &quot;&quot;pixel&quot;&quot; is 2mm in size.<br /> 【Function】The mesh pad is reusable and keeps the pores unblocked for a long time, helping to create a healthy environment for the roots.<br /> 【Easy to Install】Wrinkle-resistant polyester material, flexible and durable. Easy-to-use polyamide fiberglass mesh that won&#39;t wrinkle, wrinkle, dent or unravel - stronger and retain its original shape for longer.<br /> 【Most Advanced Technology】Polyester has high resistance to light weight, tear resistance and abrasion resistance. The mesh inserts made of polyamide are thin and dense, but also elastic enough to function, hold their shape and not fade.<br /> 【Multi-purpose】Mesh pads are used to place on the bottom of ceramic pots or flower pots with small holes to minimize soil migration out of pot drainage holes and keep your deck, house or table clean. No more messy bark, gravel or packed peanuts.
