Mr. Pen- Washable Watercolors, Watercolor Paint Set, Water C

The Verdict

There are two kinds of watercolor sets in the world: the ones you buy for yourself and the ones you buy for a six-year-old who will absolutely paint the dining room table. The Mr. Pen Washable Watercolors set is firmly in the second category — but that doesn’t mean it’s disposable. With a 4.6-star average across 229 ratings, this set has built a legitimate following among parents and teachers. Let’s break down whether that reputation is earned.

What You Actually Get

This is a 24-color pan set in a compact plastic case. Each pan is a standard 22mm round — small but serviceable for little hands. The case includes a brush, which is the typical plastic-handled synthetic that comes with kids’ sets. It’s not going to win any awards, but it holds up for basic painting sessions.

The color selection is thoughtful for a children’s set: primaries, secondaries, plus a few earth tones and a workable black. You’re not getting artist-grade pigment density here, but that’s not the point. The point is that a kid can mix a decent green without turning everything into mud.

Performance: The Real Story

Here’s where the Mr. Pen set surprises. The colors are more vibrant than most budget kids’ watercolors I’ve tested. The pigment loads onto the brush reasonably well and doesn’t require aggressive scrubbing to activate. Wet-on-wet blending works — it’s not going to produce luminous washes, but for a child’s first exploration of color mixing, it’s genuinely functional.

The washability claim is the headline feature, and it mostly holds up. On skin, the paint comes off with soap and water without needing a scrub brush. On clothing, it’s less reliable — cotton shirts will usually release the pigment in a warm wash, but synthetic fabrics can hold onto stains. One reviewer noted, “My son painted his entire white school uniform. I was ready to throw it out, but after a soak and a normal wash, it came out completely clean.” That tracks with my testing.

What Buyers Consistently Praise

The durability of the case is a recurring theme in reviews. The hinge mechanism survives the “thrown in a backpack with a water bottle” test better than most sets in this price range. The pans are also removable, which makes cleanup and refilling significantly easier than fixed-pan competitors.

Parents also appreciate the size. The case is roughly the dimensions of a large smartphone, making it genuinely portable. It slips into a pencil case or a small craft bag without adding bulk.

Where It Falls Short

The brush is the weakest link. It’s the standard fiber brush that comes with nearly every kids’ set — it splays quickly, loses its point, and doesn’t hold water well. I’d recommend buying a cheap synthetic round brush (size 6 or 8) separately. It makes a noticeable difference in how enjoyable the set is to use.

The color payoff is inconsistent across the spectrum. The blues and reds are strong, but the yellows and some greens come out chalky and weak. For a child who’s just learning color theory, this can be frustrating — mixing a yellow that barely shows up with a blue that’s too strong leads to brown, not green.

The lid doesn’t snap shut with a satisfying click. It closes securely, but there’s a slight wobble that suggests the plastic could fatigue over time with rough handling. Not a dealbreaker, but worth noting if you have a particularly aggressive child.

Who Should Buy This

This set is ideal for:

• Parents of kids aged 4–10 who want a portable, washable set that won’t cause tears when it gets dropped or spilled
• Teachers who need multiple sets for a classroom and want consistent quality at a low price point
• Beginner adult painters who want to test whether they enjoy watercolor before investing in professional-grade materials

Skip it if you’re looking for artist-grade pigment density or a brush that performs like something from an art supply store. This is a learning tool, not a professional instrument.

FAQ

Q: Does the paint wash out of carpet? A: Mostly, if you catch it while wet. Blot the area, apply a mild soap solution, and blot again. Dried paint is harder — you’ll need a carpet cleaner. Don’t let it sit overnight.

Q: How many paintings can you get from one pan? A: With a child’s typical usage (generous water, moderate pigment), expect 15–20 decent painting sessions before a pan starts showing the bottom. The set includes refill pans available separately.

Q: Is this safe for a 3-year-old? A: The paint is non-toxic and washable, so yes — but the pans are small and removable, which means a toddler could pull them out and make a mess. Best for supervised use with younger kids.

The Verdict

Buy it if you need a reliable, portable, washable watercolor set for a young artist who’s more likely to paint their hands than a masterpiece. It’s the right balance of price, durability, and color quality for the chaos of childhood creativity.

Skip it if you’re an adult or older teen who wants to actually learn watercolor techniques — you’ll outgrow this set in a week, and you’d be better served by a basic artist-grade palette.

Rating: 4.6/5 — The Mr. Pen Washable Watercolors set does exactly what it promises: it gets kids painting without turning your laundry into a modern art installation. It’s not perfect, but at this price and quality level, it’s a legitimate recommendation.
