Thank you for viewing. This is a listing for a set of 13 Mujim mat joint mats, 60x60cm, 2cm thick, for muscle training. I used these in my home gym, but I'm selling the parts I no longer need due to downsizing. There are marks from a power rack and bench. There is also some slight fading, but there are no problems with use. There is also one mat that has been cut for a pillar, and one mat where the edge has peeled off due to being pressed by a pillar. I do not smoke, and I do not have any pets. There was no eating or drinking in the home gym, so there is no dirt or odor, but please be aware that there may be some dust. The following is quoted from the site regarding the mats: Product Name: Home Gym Floor Mat, 2cm Thick, Gym Soundproof Rubber Mat, Shock Absorption, Vibration Absorption, Joint Mat, Training, Exercise, Extra Thick, Muscle Training, 60x60cm Size: 2cm thick / Approximately 61cm square size (see photo) Weight: Approximately 1.2kg/sheet Color: Base color: Blue Material/Material: EPDM rubber, EVA Set Contents: 16 mats (2 side parts/1 mat) Product Description: [Hybrid mat of EVA + rubber material] By combining EVA material with soundproofing and shock absorption and a strong, non-slip rubber material, we have created a mat with the best performance for a home gym, taking advantage of both materials! [Easy installation with joint type] Because it is a large size of approximately 61x61cm, the amount used is small, and you can easily install it by simply matching the uneven claws. It weighs around 1kg per sheet, so it's easy even for women♪ [Perfect fit with side parts] Each mat comes with 2 side parts, so you can lay them neatly to the corners! You can also cut them with a cutter, so you can install them perfectly to fit the shape of your room. [Just wipe it with a towel for cleaning] The surface is made of water-resistant rubber material, so it's easy to clean! It is a floor mat recommended for running machines, flat benches, and also for ab rollers and dumbbells because the surface is non-slip.
