Hello,My name is Manuel Garcia Ricardo. I am Cuban, but I am doing my PhD at the Leibniz Institute of Plants Biochemistry, Halle(Saale), Germany. My brother in Cuba have a business of renting lights and he asked me if I can buy for him some white-opal polystyrene sheet 70 % transparence as the kind you sell. We are interested in 2mm thickness sheet and in total 4 sqm. They can be divided as you prefer. For example I could buy 16 pcs of 50 cm x 50 cm x 2mm, they are 4 sqm in total. If I calculated right, they will be around 8,5 kg and I suppose the shipping weight around 9-10 kg. Then please, I will appreciate if you can send me e quotation for the specified sheet characteristics and please include the shipping cost too., I will appreciate if you send me a copy to my(). Do you accept PayPal payment? Thanks for your time, Wishing you a nice day,Manuel Show More
