Cross Roper Tension

I received this last week but accidentally bought the wrong size and cannot return it, so I would like to sell it. The contents have not been opened. Price negotiation is possible. Please message me before purchasing. I will explain the details.
There are 1 piece of 1200x1200 and 7 pieces of 1200x1000, for a total of 8 pieces. Parts are also included.
Please message me if you have any other questions.
