I attempted to install cushion flooring myself using DIY methods.
However, the walls in my room have few straight lines,
and this cutter seemed unsuitable for the task.
After a brief trial, I stored it in a dark place without further use.
Other items were stored similarly. As the adhesive was used slightly,
this listing will exclude the adhesive. Please refer to the images for the product's condition.

A new roll of double-sided tape for flooring is included. (Please provide your own masking tape.)

I hope this can be useful for those considering DIY renovations for their rooms.

(It seems to be more suitable for homes with flat walls.)

Thank you.
