Our large S&Ps are square, have a 2 ounce capacity and stainless steel lids. We get them from a restaurant supplier for consistent quality, and since they are restaurant shakers, the holes are all the same size. Each pair is lovingly handpainted by Lisa with her famous attention to detail. They are washable and dishwasher safe, although we recommend gentle hand-washing. Please don't soak or use any abrasives.
On average, Lisa paints over 3000 pieces of usable glass each year, many of them Salt & Pepper shakers.
