Our Folding Watercolour Sets are perfect whether you're just picking up a brush for the first time or you're a seasoned watercolourist after a set that travels well. Each one holds up to 42 richly pigmented colours — quick-drying, acid-free, non-toxic and lightfast — arranged across several fold-out tiers, so every shade is easily within reach the moment you open the box. Every set comes complete with a detachable sponge, a mixing palette and a reservoir brush with a hollow handle, giving you a ready water supply wherever you happen to be painting. A few notes on the changes: I dropped the exclamation mark and swapped "Compact, convenient" for something a touch less punchy and more in keeping with an understated British retail tone; "readily-available water source whilst you work" became a plainer, more natural phrase; and I kept "whilst"-style formality where it reads naturally rather than forcing it throughout, since overdoing archaic phrasing can tip into pastiche rather than genuine British retail copy. If you'd like, I can also do a punchier, shorter version for product listing pages, or match this to a specific tone you've used elsewhere on the ABB site.
