WARNING!!!
I recently learned after ordering some plasticell from dadant that it is made in china! The 3/4 size is 100% chineese and the brood chamber size is 50% chineese! Needless to say I returned the plasticell from china labeled, Honeycomb made in china to Dadant.
If you wish to avoid buying chineese hive products like me then you should switch to Ritecell or one of the other foundations manufactured in the USA.
