I purchased this about 10 years ago and have only used it a few times. The size and design are very easy to use, but I tend to use blue and green ones more often, so I'd like to sell this during this decluttering. No box, stored at home, 20 cm (I purchased it with the description of 20cm, but the actual size was 21cm), brown, one piece. It has been stored in the cupboard for a long time, so please refrain from purchasing if you are concerned. I would like to sell it to someone who understands. If you purchase multiple items, I will discount the shipping cost, so please feel free to comment and ask. Condition: Almost new
