18" Replacement Mat for Cutting - Durable & Non-Slip Craft Mat for Sewing, Quilting & DIY Projects | Perfect for Home, Office & Workshop Use

They are the cutting mats for the Carl 18-Inch Rotary Trimmer. No problems with them. Carl rotary trimmers and their parts are good quality.Just that the seller charged me $23.13+tax for the pack.While Carl manufacture website charges $11.32 (no tax)+$5.00 shippingThe seller charged over double what the Carl manufacture website charges.I bought 3 packs which I paid $36.34 more than the Carl manufacture website would of charged. Which is over double amount of money that Carl manufacture website charges for the same item.Some of this is my fault for not checking the manufacture website first.Just gives me a bitter taste in purchasing with sellers on Amazon. Since we, customers, should be able to trust that we are getting a fair price on Amazon. Lesson learned.
