- 5 of 5 SOSS 101 Invisible Hinges April 8th, 2026
by Richard from Mukilteo, WAThere is a marked difference between the SOSS 101 invisible hinges and those made in other countries. The quality, fit, finish and the smoothness of operation of the SOSS hinges is just superior. Yes, they cost more but is your project worth the cost in long term.

Purchased my Blum 24” drawer glides, and received them 1 week later. I was shocked by how fast my order was processed, shipped and arrived! I have three other projects planned for this summer and will definitely order all my parts for my upcoming projects
