We are one of the biggest companies in New Zealand involved in the manufacture of toiletries and Pharmaceuticals. We are in the look out of some high quality shampoo bottles similar to what you see in Japan and korea for exports into China If you have some good bottles in 450 ml or 500ml please do initially send us the pictures and then we shall revert back to you. In case you do not ahve good standard bottles we could develop a mould and manufacture the same. Look forward to hearing from you soon. Thanks and regards Harry Subu
