Which canvas bumpers

I went with the flagman canvas bumpers. They are half black and half white with streamers. I mostly use them in the winter time and they show up against most backgrounds. I use canvas in the winter since it won't break like the plastic ones trend to do at 0 or less.

Flagman bumpers are made in the USA.

the two I had in the past did not last. Weak plastic bag full of sand for ballast that broke and leaked out so now I only use for blind work.
