The small set is convenient to carry.
Color: Vivid Orange1, Size: 16pcs
It works well and has a non-slip handle. Although there aren't many blades, it's enough for a family. The accessories are small but practical.

Good for Beginners
Color: Grey, Size: 16pcs
Super easy to understand and very usable for a first time user like me. I did have to ask my friend to help me, but it was a super simple task with the instructions and good quality. Perks of working in construction lol, you get friends who know everything without needing instructions.
