I accidentally purchased both the "Double Tent Set" and the "Tent Mat & Sheet Set" at the same time. As a result, the tent set already included a mat & sheet, so I no longer need this one. I took it out of the box once to check the contents, but it's unused and only opened indoors (never used or set up outdoors). Please purchase only if you understand the situation. - New / Unused (Opened) - Complete accessories - Original box included (only opened) - Will be carefully packed and shipped as is - Will be carefully packed for shipping Size Mat size: (approx.) 260cm (H) x 260cm (W) Sheet size: (approx.) 250cm (H) x 250cm (W) Instant purchase OK. Thank you.
