Quilt Batting - Thick - 1 piece Patchwork Quilt Batting 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 item with excellent cost performance. I'm selling it because I'm no longer doing handmade projects and have no use for 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 (about 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'd like to buy more.
