- 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.

- 5 of 5 Pretty ingenious March 3rd, 2026
by Travis from Golden, COThese things are super cool and seem like they solve some problems in a unique way. But beware: they're pretty fragile! Don't expect to be able to test fit them and remove them over and over, or you'll break them (speaking from experience)

Tried finding the hinges elsewhere. Found them right away. Perfect match.

I was able to find the exact hinge needed to replace broken hidden Soss hinges in a Martha Washington cabinet. The price was reasonable. It did take a while to ship out (ordered May 15, shipping notice June 2) but then arrived quickly once shipped.

I have looked and looked for replacement parts for my cabinets and was about to give up hope, but thankfully they had the exact parts I needed. They arrived quickly, reasonably priced and I am thrilled.
