Presented on a flexible wire ring that unscrews so that you add more than one set to the ring, or even add a second ring to make a much larger set.
The main heart shaped hole will easily cater for a full skein of floss. There are two smaller circular hole either side to accommodate any off cuts that you may have as you stitch.
Great idea. I was surprised that the ring holding the drops could not be opened/closed so that different numbers of the drops could be used on different occasions. Have cut through the ring and am using a knitting stitch holder..
