This current-generation 52gsm stock faithfully replicates the slow-absorption properties that enthusiasts demand. By allowing wet ink lines to pool and dry naturally on top of the cellulose fibers rather than soaking instantly into the core, it concentrates dye molecules on the surface. This chemical behavior uncovers a dramatic spectrum of color properties—from the bright crystalline sheen of saturated inks to the delicate shade-shifting properties of multi-tone pastel lines.\u003cbr\u003e\u003c\/p\u003e","brand":"Tomoe River","offers":[{"title":"A5","offer_id":53242890125640,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false},{"title":"A4","offer_id":53242890158408,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/inkwellartsupplies.com\/products\/tomoe-river-loose-sheets","provider":"Inkwell Art Supplies","version":"1.0","type":"link"}
