Solidz PVA bags are among the most intuitive on the market: produced by Korda in the United Kingdom, they use the highest quality neutral pH PVA "film." They dissolve quickly once immersed in water, leaving no residue. At the same time, they are extremely robust during preparation and do not tear or break as long as they are kept dry. Two bags can be used together in very deep or warm waters to ensure the bag reaches the bottom intact before starting to dissolve. They are available in four different sizes to suit all fishing situations, from long-distance casting with the XS bags, to using a larger amount of bait in a very limited area with the L size, with S and M sizes being intermediate and suitable for other uses. Solidz bags are sold in a resealable pack that protects them from moisture. A pack of XS and S sizes contains 25 PVA bags, while packs of M and L sizes contain 20.
