My dummy clips are made from the highest quality beads, from the best manufacturers of wooden beads  and wooden clips in Germany, country well known for their high quality products including wooden toys. All the beads are free from toxic substances, oxide and nickel. They are also resistant to sweat and saliva which is very important as babies will carry these products on their sensitive skin and will chew them quite a lot, so I really wanted to make sure that simple wetting of the lacquer will not produce any wear or detachment. I also use safety wooden clips with 3 ventilation holes. Do not buy clips without them, as they may represent a choking hazard for the kids! All the dummy clips are made using 2mm satin cord which meets all the requirements for safety regulations. Also my dummy clips are approximately 22cm in length - this is the maximum legal length to avoid strangulation risk!  I use as well safety beads (first & last bead on the dummy clip).
