Split Cups for Paint Pouring, 4 Pieces Reusable Silicone Split Cup for Acrylic Paint Resin Pouring DIY Making

These cups are flexible which makes them difficult to pour straight lines. You end up with wobbly ones. That might be fine for some of you though.

Very flimsy. When picking up the cup to pour the sides collapse in causing the resign to spill out on your hands. Total waste of money

I hate leaving bad reviews, but these cups are so flimsy it's hard to keep hold of them as you're pouring the paint onto the canvas.

Very flimsy and not good for paint pouring.

These were a bit hard for me to hold. They are not hard plastic. But still ok
