I bought 100 buckets of 10 ltrs from this supplier for sample only ,the material provided by them is of worst quality and they do not even care when i complaint them about the quality they provided me ,inspite of it they told some stuff like you hit the cap more hardly or buy some silicone hammer or something .I also buy it but after that also every bottle is leaked.I bare a huge loss because of them .Never buy from this supplier.
