Review on 📐 Bloc Loc HST- 4.5x4.5 Inches Half Square Acrylic Triangle Ruler by Morgan Gilmore

My ruler arrived on time. This is a unique ruler whose central diagonal part is hollow. This hollow part allows the ruler to sit snugly on the seam of the half-square. Triangle and allows for easy alignment, both halves of the square line up perfectly. Other rulers I sometimes move around when aligning a block and end up with a slightly crooked corner. Not with this ruler - perfect angles every time I have many rulers but this is my new favorite.
