Recently I have purchased 5litre Methyl ethyl ketone Chemical from Ibuychemikals.com as it is offering discounts on these items. The best thing about this website is it gives the dates when I will receive these items and to my surprise I receive these items before this date. Also all the (MEK) are in good condition. Whatever they have displayed on their website for the product it fulfills the expectation. Also their customer service is very good. So I will definitely recommend this site for online chemical purchasing.
