Question: What color are they?
Document: Opaque &#34;color&#34; is perfect. I put it in my mother's kitchen and she didn't even see it. It fit between her countertop and the range perfectly. We were fortunate that the length was just right and the item doesn't move at all.
Perfect for keeping stuff from falling in between the oven and counter. You can easily wash it or throw it into the dishwasher. Make sure that you get the right color. I originally purchased the clear, but then I bought the black instead since my countertop and stovetop was black.
I've had one for the left side of the stove but could not find the other one. I did not want a color to detract from the quartz counter top or the stove. The one I received is closer to an L than a T shape. Maybe 1" by 3" on the sides.
Have had several different types of  these gap covers, and this is the best one yet. I like that they are soft, and lay flat. Old ones had a mind of their own! The opaque/clear  color is perfect, and the other potential problem of staining did not happen, even with tomato sauce , can't ask for more than that!
This product works. I had trouble because my stove was tighter on one side, so it did not fit in as well. But that was not the products fault. The only thing I was disappointed in is that I expected them to blend better into the color of my counter top and stove. They are very noticeable and I wanted something to blend in. I thought they would have been a more clear to blend.
The item is good quality but not as pictured and therefore useless for my needs.Additionally, after factoring in shipping if I return it i'll get less than $2 back, so I'm just giving it away, but I would not have purchased it if the pic was correct. is not L shaped as pictured, but T shaped. Also it is not solid color, but see thru.
works well and stays in place better than the plastic ones with magnets. Only improvement would be if it came in black that matched my counter
this came but is bulkly and unsightly on my countertop ---will not use
overpriced , assumed for the price it would be a pair not a single unit.
only one comes, and it is a piece of junk. still keeps things from falling. the price dropped by 45 percent the day after i bought it. Amazon gave me the difference back
Answer: They are semitransparent. I wash them in dishwater and they are very easy to clean.
