I liked the shipper's placement of this material into a separate clear polyethylene zip lock baggie that was then set into the heat sealed aluminium lined shipping baggie. However, the shipper needs to please note: the baggie used was too SMALL and the zip closing inside baggie seam was NOT sealing well enough to prevent spillage to the larger container. The result was a mess... minor advice, if used, then please fix a bigger stronger inner bag. Inner baggie maybe is not needed? The MALDI-TOF spectroscopy tests we performed, show this is an excellent and pure product. Thank you for your intended thoughtfulness, sorry about the package failure, and please continue selling a very great product!
