Cardboard Tubes, Poster Tube, Empty Paper Towel Rolls, White, 120 Pack

Great for crafts. Nice and strong.

They’re okay they work for curtains

I saw some other reviews that it won't work as curtain fold spacers but they do with some adjustments. I didn't cut the length of them down. I did cut them length wise from one end to the other to split them so I could slip them over the curtain rod. On both ends I cut tabs into them by making a series of 1/4 cuts. Then I folded the tabs out around the ends. Don't make the tabs too wide because they are more difficult to fold. The tabs keep craft rolls from slipping through the curtain grommets. The rolls seem thick enough that they will hold up pretty well especially if the curtains are some you don't open and shut alot. I used to have these separated with pieces of pool noodle but it made them too difficult to open and shut when needed and I could see the colored noodles through the grommets in some places. These move pretty smoothly and I don't notice them at all. Very happy with how these keep the grommet folds in place and of even size.

Not good for curtains good for crafts

These are not a good fit for grommet style curtains. The diameter is too small and will slide through the grommets. However, if you are a crafty person or have kids that do crafts with toilet paper rolls, these are a thousand times better - thick and sturdy! Both comparisons in the video attached.
