These stainless steel coasters work well and won't warp or break like cheap plastic coasters. However, the manufacturer had to think a little about how to store the nibs and how to retrieve them from the so-called "handy" plastic box in which they are supplied. With four sizes and only two compartments, the contents get tangled and slip out quickly. in the box, making it surprisingly difficult to pull out one or two with your thumb and forefinger. There's also no way to prevent them from spinning sideways and falling too low to get at the smaller sizes. It's an unnecessary frustration to get dressed in the morning. It should be easy.
