Safe and stable material: these vinyl swim kits are made of PVC material, waterproof, durable and firm in use, hard to carry and break, nontoxic and odorless. DIY versatility: you can DIY these vinyl rubbers for boat with scissors in different shapes or sizes to meet your different needs. Easy installation: selfadhesive patches. Due to the selfadhesive backing, you only need to clean and dry the damaged surface of the inflatable product before using the PVC patch, then tear the product, then stick this PVC patch to the desired place, and wait until the adhesion is firm. Subtle results: the patch can help holes in your inflatable items effectively, and you can find that the trace is not close to visible. Use scenarios: On the water: patch punctures on inflatable boats, rafts, kayaks, or paddle boards to stay afloat during trips. At home or poolside: pool floats, air mattresses, or other PVC inflatables for quick reuse. On outdoor trips: field camping inflatables or other PVC water toys when needed.
