Premium Bamboo Sushi Rolling Mat - 10.5 Inch Sushi Maker Kit for Perfect Homemade Sushi Rolls | Authentic Japanese Sushi Mat for Beginners & Chefs | Ideal for Parties, Meal Prep & Asian Cuisine Lovers

I picked these because they're a bit larger than standard rolling mats. I like having a bit of extra space to work with. I used them tonight to make 12 large rolls and they worked great. One other review mentioned that one end of twine holding them together was waxed and glued, and came apart, but that may have been an earlier version. Mine are full length threads, looped around one end and tied on the other. No wax or glue holding the twine on.They're well constructed and should hold up fine as long as they are protected from food contamination. They aren't exactly easy to keep clean long term. To that end, as others have said, I recommend wrapping them with saran wrap or placing them in a gallon zip-lock to keep food off them while rolling. That will keep them in new condition for years.
