Review on 20PCS 18Mm Glass Table Top Bumpers - Non Adhesive Medium Rubber Anti Slip Pads by Patrick Clifton

These glass spacers are very nicely made and of high quality. They adhere to the glass and the tabletop well and prevent the glass from sliding. They are barely noticeable under the glass. The delivery was very fast!The reason for my only giving this four stars is that they are much thicker than similar pads that we've used in the past - perhaps I should have realized that before purchasing. As a result, there is about 1/8" space between the table and the glass which is great for air circulation but tends to make for greater "noise" as things are place on the glass surface.Assuming the thickness is not an issue, I would highly recommend this product.
