Melted together
Came as a 4 pack.  The first 2 were fine (all packed separately). The last 2 looked like this when I went to use them a month later.  Contacted the seller who blamed me for their condition and would'nt issue refund or replacement. The 2 that were usable we impossible to remove/untape from my dog, it had to be rolled off.
