【New Unused】Gap Pad + Mattress Band Set with Washable Cover - Connectable

I purchased this on Rakuten for ￥5980, but my bed has a step, so it's unusable. I'm listing it here. It hasn't even been taken out of the box, so it's no different from new! ?

Here is a quote from the Rakuten product description:

A washable mattress band set with an extra-wide 30cm size.

- Product Name: Gap Pad x Mattress Band Set
- Width: Extra-wide 30cm
- Sales Volume: Cumulative sales exceed 30,000 sets
- Washable: Washable mattress band

■ Great Value Package with Two Popular Products
This is a great value package that includes the Mattress Band to securely fasten two mattresses, and the Gap Pad to fill the space between them. Both are popular products!

■ A Set That Covers Each Other's Weaknesses
With just the mattress band, the mattresses won't separate, but the gap between them isn't completely filled. With just the gap pad, the mattresses separate, causing the gap pad to fall out. Based on customer feedback like this, we created a set that covers each other's weaknesses by combining these two products.

■ Mattress Belt Designed for Resistance to Loosening
Lifeest's mattress band is the latest 2021 version, improved based on customer requests. By reducing the sheen of the material, it's less slippery than before, and by lightening the buckle, it's less likely to sag.
