Both are 12 mm boards, CNC cut, and denser than standard MDF. Grey Valchromat is coloured all the way through and is the material we recommend. Moisture resistant MDF costs less and holds square just as well.

these 3D squares are a total game changer. For over 20 years I have been making cabinets, wardrobes and shelving units with dominos as the main joining system. I had used Bessy corner clamps in the past as well but you were always battling between two corners to get the square. I saw the advert on line for these squares and thought I'd try them out. In the first place they are remarkably strong and rigid holding the two pieces at 90 degrees spot on allowing you to get the screws in place quickly. However the Eureka moment was when I realised that you can place the Festool style clamp in position, ready to receive the second piece of MDF, (As the design sort of locks the clamp in the ready position without it falling off), and then lock the clamp, all one handed whist your other hand holds the second piece of MDF! Just genius and saving loads of time. Four 5-piece cabinets as the base of shelving units would have taken half a day with the dominos and clamps and glue up. I was finished within the hour with these squares. Then there were the shelving units themselves with one fixed shelf for strength in all of them and a top section. Again an hour to build. I had done 3 days work in less then day!
They look great in the black MDF they are very well made, easy to put together, feel great and they all fit into a Festool systainer box to keep them safe and clean.
Every now and then you come across something that changes the way you do things for the better. U-Scribe jig's click dominos does what it says one the tin! The Greco QuickShot paint sprayer makes painting cabinets almost fun! The Souber door lock mortice, (Big thanks to Robin Clevett for the video},more than halves the time it takes to fit locks, and these Freebird 3D squares have drastically reduced my time on site and improved my carpentry making tenfold. Would highly recommend them to all carpenters.
This is an excellent review Richard - we appreciate you spelling out the experience of starting to use them, and the mental shift away from unnecessary and time consuming methods that reduce productivity for most cabinets. Best wishes to you!
