Arghhhhhhh Has anyone else experienced this problem I am sure you must have just wondered if anyone has a solution. I have tried several different makes of nail tip glue. Everytime I use it I clean the nozel properly and replace the lid. The next time I go to use it it is blocked. I have tried to unblock with a pin that doesnt work snipped the end of the nozel which works for that time but then it dries up again inside of the nozel, (they are all stored upright). However there is still loads of useable glue in the bottle. I end up having to throw away loads of these and always have a store of new ones just incase. I am now mad with having to keep getting new ones each time and wasting so much!! What do you do when you get this problem?? Your help would be greatly appreciated.
