I ordered one bottle each thin, medium, and thick glue. When they arrived, I found the bottle of medium had leaked during shipment and everything in the box was stuck together. I was able to get everything broke loose and cleaned up pretty well and tightened the cap on the medium bottle. I used the thin glue that day and it worked great. I then placed all three bottles on my glue shelf. The next morning I found the medium glue had either leaked or oozed from the bottle, leaving a sizable puddle on the shelf, sticking several nearby items together and dripping onto my shop apron hanging under the shelf, rendering it unusable. I contacted customer service explaining the situation and requested a replacement bottle of medium glue, as I had to dispose of the one I had. I have received no reply. Good glue, but unfortunately I probably won’t buy again.
