Nishimatsuya Joint Mats 40 pieces 31.5 x 31.5 with side and corner parts

These are interlocking mats purchased at Nishimatsuya two years ago. While there are various combinations, all pieces measure 31.5 x 31.5 cm.
The thickness is about 1 cm.

Please refer to the images for details:
- Beige: 12 pieces
- White: 12 pieces
- Light Beige: 4 pieces
- Dark Brown: 4 pieces
- Cat Pattern: 4 pieces
- Fish Pattern: 4 pieces

- Edge pieces: 11 pieces
- Corner pieces: 4 pieces

These were used as a playmat for a baby for six months. There is some sign of use, but they are mostly clean with very little dirt.
I have taken photos of any areas of concern (images 5 and 6).

The mats will be shipped in a cardboard box, and the interlocking mats inside will be wrapped in a plastic bag. Bubble wrap will not be used.
Please only purchase if you understand that this is a used item.
Thank you for looking.
