There is no defect on this. It is overstock.
All door mats are painted with a premium rubber-based sealant paint for a long-lasting finish.
Latex Backed Mats
These mats are premium quality made from 100% natural coir that has been mechanically twisted for less shedding and with a latex backing which reduces the risk of slipping and helps the mat stay flat to the floor.
We recommend our coir door mats are used indoors or in a covered porch area, to prevent discoloration of the coir. Simply shake the mat out to clean it.
