OwnMy 16mm Hidden Brass Barrel Hinges 4PCS, Concealed Box Hinges Invisible Furniture Hinges 180 Degree Opening Angle Cabinet Hinges for DIY Jewelry Box Hand Craft

EXACTLY AS ADVERTISED. ARRIVED NEXT DAY AS PROMISED.WOULD DEFINITELY BUY AGAIN.

These barrel hinges are cheaply made and broke when trying to install. I do not think they are truly 10mm, since they would not fit a 10mm hole drilled. When trying to test fit, one of the hinges broke and I could not get them installed on my test piece. I also noted that they have no screw to tighten or secure the hinge after installation. I'm glad I tried them on a test piece first, or I would have ruined my box I was installing them on. I could not get them to work so I ended up ordering a better made barrel hinge from Rockler that works great and was easily installed.

Neat little hindges for those fancy boxes you wanna make, but want a more hidden hindge look

Very nice and sturdy. You MUST secure and use a 10mm drill bit for a snug fit. This is a MUST!!! Else the hinges will wobble and you won't be happy.

Smooth and easy to install.

I can't give these one star, because maybe its my drill bit (10mm also bought on Amazon). These don't seem to be 10mm and they look suspect, maybe used, or not really made well. No instructions either, i just used some instructions I found on the Internet. I even tried my 27/64 non metric bit, and it didn't fit, the hinge was to big. I must say, I can't understand why I continue to buy stuff on Amazon. What do they say--the definition of crazy is doing the same thing over and over again and getting the same results. That pretty much sums up my experience with Amazon.

Got what I ordered and on time. Thanks
