Beautiful Pine Garland
Material Type: Norfolk Pine Garland, Size: 6FT(2 PCS), Material Type: Norfolk Pine Garland, Size: 6FT(2 PCS)
I bought these and they are beautiful on my mantel. They look real. They are easy to mold into position. When hanging them one of the strands pulled apart so I would be cautious about pulling them too tight. I was able to use electrical tape to join the pieces back together again and wrap the material back around the joint and continue to use them. I would still purchase this again despite the issue I had.

Very realistic, but easy to clean.
Material Type: Norfolk Pine Garland, Size: 6FT(2 PCS), Material Type: Norfolk Pine Garland, Size: 6FT(2 PCS)
I thought it was going to be the more realistic material but it’s plastic. Honestly I don’t mind because it looks very realistic but since it’s plastic it makes it easier to clean. I love it, it’s thick and it gives the realistic vibe falling, I got it for the my fireplace and it looks great.
