【Earthquake Protection: Heavy Duty Commercial Use: 130 Sheets (5x5cm)】Anti-Tip Gel Mats

I renovated my self-employed stationery store and ordered these for business use, purchasing them in bulk. I have nearly 130 unused sheets, so I'm listing them as part of decluttering.
The large unopened packs are completely sealed from when I purchased them. The ones that appear yellowish are the unused portions from opened packs. They have some discoloration due to age, but the adhesive strength is perfectly fine, so I'm including them as a bonus.
These are 5cm x 5cm gel-type sheets with clear film on both sides that you peel off before use. They have very strong adhesive power, capable of withstanding earthquakes up to magnitude 7. Individual sales are not possible, but please consider them if your company, school, or store has a need for many of these.
