    Hard core velcro

I used this to secure a plastic panel under my car. It is an excellent product with very strong glue.

    Super strong and comes with a great quality cutting tool
  

*by C***E on Reviewed in the United Kingdom on 12 August 2023*

these fasteners are really tight locking and a good size. I used these for my desk organisation and cable management and they worked like a charm! It comes with a cutting tool also, which unlike others, is metal and so much more robust. Highly recommended!
