Quilt Batting, Thick, 1 piece Quilt Batting for Patchwork MW-14P Size: 105 x 100cm, 1 piece Thickness: Approximately 2.5mm Material: 100% Polyester This is a product from the manufacturer Marushin, and it's a highly recommended product with excellent cost performance. I am closing my handmade business, so I'm offering this for sale as I no longer need it. According to the original description, the thickness is about 2.5mm, but I measured the thickness with six layers and it was about 2.4cm (approximately 4mm per piece). I've had experiences where cheap quilt batting bought from 100-yen shops was unusable, but this manufacturer's quilt batting has a good thickness and is inexpensive and easy to use. It has a slightly firm and soft feel. (It's not a supple, soft, and fluffy feel, nor is it a crisp, hard type.) This is a single piece for sale, but bulk purchases of two or more pieces are also possible, so please comment if you are interested.
