Instant purchase is OK. First come, first served. No holds. If paying at a convenience store, please be sure to inform me of the payment date in the comments. Please refrain from purchasing if you are nervous about used items. This is a mat that was used in a personal gym. Mainly, the parts that machines were not placed on were replaced with new ones, so the parts used in the aisles are being sold. If you want to create a stretching area at home, or if you want to put it under a bench, etc., please consider it. It's heavy, so it will be shipped in units of 3 sheets. The photos are of 16 sheets laid out at my home, so I will ship the remaining ones. This is a professional-grade mat.
