“They’re (SOSS Invisible Hinges) are super sleek (and) takes your furniture building up to the next level. The cool thing about them is that they’re not that expensive and they’re not that hard to install.”

Michael Alm

“We love your stuff (SOSS Door Hardware)! Use it a lot.”

Sean Patrick Builders

“A little bit pricey but so durable and easy to transport that my 11 year old could take it out to the sidewalk, set it all up and then put it away by himself. This was better than any other ramp I found (as most were way too narrow to ride bikes or scooters over) and this one I feel is safe and very, very stable in comparison. I am really happy with this purchase.”

Larry, Customer that bought Landwave from Amazon
