very good quality! reminds me of an Estonian brand that i just adore but have trouble forking over $100 for. well packaged. I have ordered 8-10 bottles and they have all arrived fresh good to the last drop. the fume factor is medium. clients don't notice it but for me there is the runny nose and occasional watery eye during application towards the end of the bottle. otherwise I love everything about this glue. retention is excellent. 3-4 week infill and most all are still attached but requiring removal as they have grown out to the end!
