I have to move this stuff. I have 5 large healthy and dense mats. 2 are in excess of 8X12, 3 are in excess of 5X6. The 2 large are $20.00 plus $8.00 shipping and the 3 others are $15.00 plus $6.00 shipping. I will also make up,some 3x3 portions for $5.00 plus $6.00 shipping. This is the healthiest Riccia I have seen lately. You will not be disappointed. I will also consider trades.
