This is a gymnastics mat from KaradaStyle. It will be shipped in the original box as it arrived. I was using the beige one as a baby mat and intended to purchase another, but I accidentally bought the greige one. This mat is 3cm thick, not too thick, and has a solid construction that I am very satisfied with. It's also easy to clean. When I was using joint mats, dust and dirt would inevitably fall through the gaps onto the flooring, which was a hassle to clean. With this mat, the dirt accumulates in the gaps, so you can simply stand it up and tap it to remove the dirt, then finish with a vacuum cleaner. It can be used as a gymnastics mat even as your child grows, so it can be used for a long time. If you're looking for one, how about it? The shipping cost is included, so please refrain from price negotiations.
