Due to health issues, i closed my business early 2015 until recently reopening. Have purchased and used Bayousome's White HDPE Modified Boston Rounds for many years for many years (2,4 and 8oz) and love them. Had even lost a case of the 8oz bottles I'd filled with product and discovered them afterTWO hard West Virginia winters and a couple of summers with no temp. control! Amazingly, no leaks or issues whatsoever. Tough bottles!
