If I could give 0 I would. Spots are visible behind fabric used. Could see it through packaging. Looks like black or a dark glue. If the glue wasn't visible they would have been fantastic for the purpose. Ordered these for product photos and now I am out $ spent, time and will need to buy different set since these will NOT work at all and not allowed to return even though they were Prime and fulfilled by Amazon. Added pics to show you and these were just taken from my phone camera. Not even going to bother with DSLR. Not worth the $8 or time to spend editing. Seriously disappointed with product, seller and Amazon on this one.
