Staedtler 24 Colored Pencils vs. Watercolor Pencils: A Procurement Manager's Honest Comparison (Based on $3,200 in Mistakes)

The Comparison Framework: Two Product Lines, Very Different Jobs

I handle office and design-supply orders for a mid-sized firm. If I remember correctly, we've spent roughly $3,200 on colored pencils over the past three years — and about $890 of that went straight to the trash because I ordered the wrong type. It wasn't a quality issue; it was a mismatch between what the pencil could do and what the user needed.

This article compares Staedtler 24 Colored Pencils (the classic Noris or Mars Lumograph color series) with Staedtler Watercolor Pencils (the Noris watercolor or Aquarell lines). If you're sourcing for an architecture firm, a design studio, a school art department, or just stocking a general office, you need to know the difference — because vendors won't tell you. (Should mention: I'm not saying they're dishonest; they just assume you already know.)

Here's what we'll cover:

• Usage scenario: dry vs. wet application
• Color payoff and blendability
• Durability and sharpening behavior
• Cost per unit and total cost of use
• My personal mistake that cost $450 in wasted supplies + a 1-week delay

Dimension 1: Usage Scenario — Are They Interchangeable? (No, and Here's Why)

Staedtler 24 Colored Pencils (Standard)

These are dry wax-/oil-based pencils. They lay down color on paper, and that's it. No water activation. You can layer them, blend with solvents (like turpentine), or use them for line work. They're ideal for:

• Technical drawings and schematics (color coding)
• Sketching and illustration that doesn't involve water
• Projects where smudge-proof finish matters once dry

Staedtler Watercolor Pencils

These contain water-soluble binders. Draw dry, then brush water over to create a watercolor effect. They're designed for artists who want the precision of a pencil with the wash of a brush. Good for:

• Mixed-media art, watercolor studies
• Illustrations where gradients and soft edges are needed
• Educational settings where students explore wet techniques

The critical difference: You can't treat watercolor pencils as regular colored pencils and expect them to perform identically. The binders are softer, and if you apply water accidentally (or if a user expects dry fastness), the results are disastrous. I learned this the hard way.

“I said 'order standard colored pencils for the draftsmen.' They heard 'watercolor pencils because the designer likes effects.' Result: 24 sets of watercolor pencils delivered to a technical drawing team. $450 wasted, plus a week of frustration using pencils that smeared when they tried to erase. That's when I created our pre-order checklist.”

Dimension 2: Color Payoff and Blendability

Let me rephrase: both lines produce rich color, but the texture and final look differ dramatically.

• Standard 24 colored pencils — Opacity is high. Layering works well if you use light pressure. Blending requires solvent or a blending stump. The finish is matte, slightly waxy.
• Watercolor pencils — Dry application looks lighter and chalkier. That's normal — the color activates with water. Once wet, the pigment spreads and becomes vibrant, with transparent layers similar to pan watercolors. The dry-on-paper payoff often disappoints new users.

Most people don't realize that watercolor pencils are purposely less opaque when dry. Two years ago, a new hire complained that the $24.99 watercolor set looked "cheap." I had to explain that they weren't meant to be used dry. (Oh, and we'd already bought 12 sets. $300 down the drain.)

In contrast, the standard 24 set works immediately — you get bold lines from the first stroke. If your team needs instant, reliable color for floor plans or product sketches, standard is the safe choice.

Dimension 3: Durability and Sharpening

Here's something vendors won't tell you: watercolor pencil leads are softer and break more easily during sharpening. The binder is water-soluble, which makes the core slightly more brittle than the wax-based standard leads.

• Standard colored pencils — Harder core. Holds a fine point for longer. Less breakage. Suitable for mechanical sharpeners in high-volume use.
• Watercolor pencils — Softer, bigger diameter leads. Require manual or gentle sharpening. Frequent breakage if users force them into auto-feed sharpeners.

In one study (my own informal log over 18 months), we saw 30% more breakage on watercolor pencils compared to standard, despite the same sharpening equipment. That added to cost — broken tips mean shorter pencils, more waste, and reorders sooner.

According to Staedtler's packaging, watercolor pencils are recommended for manual sharpening. But who reads the fine print when you're ordering 50 boxes for a school district? (I should add that this is a common oversight in bulk procurement.)

Dimension 4: Cost Per Unit and Total Cost of Use

Prices as of March 2025; verify current rates.

• Staedtler 24 Colored Pencils (Noris Club / Mars Lumograph color): Approximately $12–$18 per set from major distributors. Breakage low. Lifespan: typical office use, 3–6 months before sharpening wears them out.
• Staedtler Watercolor Pencils (Noris Aquarell): $16–$24 per set. Higher breakage means effective cost up to 40% more per usable inch of lead.

But total cost isn't just purchase price. If you order the wrong type, you lose the value entirely. In Q1 2024, I ordered 30 sets of watercolor pencils for a contract illustration team that needed standard. That mistake cost $720 in product + $150 in rush shipping for replacement. Credibility damage? Priceless. Now I keep a comparison card taped to my desk.

“The question isn't 'which is cheaper.' It's 'which is cheaper for your use case.'”

Dimension 5: The Surprise Twist — What If You Need Both?

Here's the counterintuitive finding from our procurement history: some departments actually benefit from a hybrid approach. For example, an animation storyboard team uses standard pencils for rough sketches, then watercolor pencils for final color frames. But they know the difference. The problem only arises when you standardize one type for everyone without checking usage.

Industry in evolution: five years ago, watercolor pencils were niche in K–12 schools. Today, more art curricula include wet media exploration. But the procurement staff often haven't updated their approved product lists. (Proof: our own purchasing database still listed 'colored pencils' generically until I fixed it after the $720 mistake.)

Final Recommendations: Which to Stock?

Don't choose one — choose based on group:

• If your users do technical drawing, diagrams, line work, or general coloring: Staedtler 24 Colored Pencils (standard). Reliable, durable, immediate color.
• If your users are fine artists, watercolor enthusiasts, or educators teaching wet techniques: Staedtler Watercolor Pencils. But only after confirming they understand the wet activation.
• If you serve a mixed population (e.g., design agency with multiple departments): Stock both, but label clearly. Use our checklist to prevent mismatches. It has saved us from four potential errors in the last 10 months alone.

And if you're the person placing the order — get written confirmation of the exact product type. Verbal agreements vanish. (That's a lesson from $450 down the drain, Q3 2023.)
