Firstly, I must say that I had read in advance better must. That this is to stickers, I only found during the delivery. When the first shock was then overcome I glued the first owl on my existing silver Waschbesckenstöpsel. Unfortunately, the label raises yet again a small bubble at the edge. No matter how well I carefully and I do that. For the sticker holds still very good. About the small bubble at the edge of time I see.
