What a beautiful build overall, Mr. Raper! 😍 We have been testing and fine-tuning our Ulta-Mat and Mega-Mat System for almost four years now. This system is the first "Over the Carpet" kit, and the testing phase is now complete—it's time to produce! Our lead times are improving, so please bear with us; we promise to deliver both style and quality. The machine times for these patterns are absolutely mind-blowing! 🤯 P.S. No, it will not cause your carpet to mold or develop mildew. Just take care
