If you have a cameo o cricut and work with vinyl you already know what this are for.

The hook is not very useful when compared to a metallic one but is cheap and better for kids in my opinion. When print use supports.

The scrap collectors come in 2 types. A very thin one and the second with thicker columns. Choose the one you like. But I recommend make them bigger, the original size is very small. The holes are there because I have a resin 3D printer.
