{"type":"firestarter.listing","listing":{"id":"lst_0nhzSIXs","product_name":"Carrot - Calligraphy Pen","category":"Calligraphy","description":"No more calligrapher's claw! \nIntroducing, the new 'Carrot', designed for those who like a compact pen holder and a lovely curved body for improved grip and stability. It takes all the best features from my much loved curved Flourish and sprinkles in some new elements.\nFirstly, the weight, it will surprise you (in a good way!). Once you put pen to paper you'll notice how the weight increases stability and your nib, in turn, will glide across the page.\nThis reassuring weight paired with the body shape of the carrot will mean you barely have to hold the pen when you write (it will do a lot of the work for you) helping you to avoid the dreaded 'calligrapher claw' and improve your technique in the long run.\nThe pen is also fitted with my unique universal flange design which holds almost every kind of nib (big and small) and allows you to adjust the angle of the nib, further increasing the 'glide factor' of your writing.\nOnce you have the pen in your hand I am confident that you'll appreciate the true quality and craftsmanship that has gone into each design decision. Made from precision machined aluminium and brass, it's my hope that it will be something your grandchildren will happily be using in years to come.\nI'm really proud of the Carrot and hope that you truly experience the joy of writing with this lovely little pen.\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/products/carrot-calligraphy-pen-pink-lemonade-seaglass-wisteria.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-all-colours-annotated.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-pink-lemonade.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-sea-glass.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-old-rose.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-wisteria.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-wisteria-packaging.jpg?v=1745323727","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/carrot-oblique-midnight.jpg?v=1745323728"],"price":82,"currency":"USD","in_stock":true,"inventory_qty":49995,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:24.241Z"},"share_url":"https://firestarter.network/l/lst_0nhzSIXs","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
