This is a maternity adjuster band from Nishimatsuya. I purchased it at a store around the fall of 2019. It's convenient because you can still wear your existing pants even when you're pregnant. ⚠️The instruction manual in the 6th photo is borrowed, and only the item itself will be shipped! Please understand. There is a feeling of use due to several washes, but the elastic hasn't stretched and the buttonholes haven't widened, so it can still be used. The fluffy material is warm and suitable for autumn and winter. Please understand that this is a used item.
