FTVOGUE4Pcs/Pack Hidden Furniture Hinge Brass Concealed Barrel Wooden Box 8mm 180° Opening Angle for DIY Jewelry Box Hand Craft

I have used these hinges on 2 projects - nice material!I decided to make a jig to get the holes in the right place.This was my first attempt.(Best to have the holes in the jig the same size as the hinges.Enlarging a small hole in wood doesn't always work out well!)

Look great! Measure twice cut once...you need to spend some time making sure your holes are laid out perfectly. I would recommend watching some YouTube videos on barrel hinges.

These hinges look well made, clean no burrs, they are a little stiff but operate well.

The hinge completely fell apart within the bullet. There’s no way to fix it since it’s so tiny. Tried to return it, but they wanted me to take them out of the box and send them back. These aren’t meant to come out once in the very snug hole. Doable, just not efficient for $12. Very disappointed because these seemed to be an excellent solution to this small box.

Well, when done correctly, barrel hinges are beautiful. But when installation is even slightly less than perfect, they suck. And they'll probably break, or break your wood, or look crappy.IMPORTANT NOTE: These are not 8mm diameter. They are closer to 8.5mm. This is a perfect example of what I mean. The hole you drill needs to be EXACTLY the right size, otherwise these will not go quietly. Not a thousandth smaller, and too large quickly has them swimming. Use calipers. Buy extras. Test on scrap. If this is your first experience with these, you're going to mess up and probably break a few, possibly need to start your project over.

These hinges worked as expected. Holes and spacing must be exact.

Great hinges - I made my engagement ring box with them!

I bought the hinges for the box pictured. Hidden hinges like this are a little tricky to install and one must measure very accurately and possibly use a conical insert in the first hole to mark the position of the opposing hole.Although they work well, they did not have a locking mechanism to lock each side of the hinge in the holes. Instead one must rely on a friction fit or install with an adhesive (not removable.). If I buy more hinges I’ll be looking for that locking feature.

These are decent. I used one set on a wooden fly fishing case and another on a wooden jewelery box. The function well for the price but are missing some of the fit and finish of a more expensive product (to be expected). Note that installation has to be VERY precise. I suggest a drill press. They need to be mounted very close to the edge of the wood and you still need to chamfer the back edges to get enough clearance to open.
