Simply outstanding! I have this cork, suitable for the test tubes, which are offered here, ordered. The corks are secure and seal the jars so very well. Since the cork about 8mm protrudes from the test tube, it is easy to dissolve it again!
About the service: I'm rarely one so uncomplicated seller meets. I have the seller my "problems" with the order and informed, get help within two business days, without question! Thanks a lot for this !!
