  • Exactly what I needed to add bookshelves!
Size: 20 mm Color: Black
Ordered for bookshelves. Easy to use. Great quality/ size was perfect for our shelving. Lightweight but sturdy.

  • Good buy, won't be disappointed

Solid, quality feel

  • Strong brackets for small wood projects
Size: 20 mm Color: Black
The stainless steel brackets are sturdy, with a clean black coating. Screws included are adequate for light furniture, shelves, or box repairs. At 20mm they’re compact—best for smaller joints rather than heavy structural work. Verdict: Handy and reliable for DIY or furniture reinforcement.

  • Brackets are good and screws are a bit weak.
Size: 20 mm Color: Black
The brackets are study and well finished. The screws (as would be expected at this price) are easy to strip and of a relatively soft metal. They are usable, but care is needed. I bought 3 packs and they worked well.

  • Works well!
Size: 20 mm Color: Black
Did everything i needed. The size is perfect for cabinet drawers in thr kitchen. They are very stable and have held up exponentially! The look of them is just beautiful! They function as they are supposed to. THey have remained stabilized

  • Exactly What I Needed
Size: 20 mm Color: Black
The cheap plastic brackets broke off a dresser so I repaired it using these. The only down side would be that you have to buy 40 when you need 3. For the price, it was worth it to be able to use the dresser again.
