Compare Plus-Plus bulk bags and Custom Mix sets. Learn which option fits your color needs, budget, and building style so you can choose confidently.
Quick answer
Choose Plus-Plus bulk if you need a large quantity of a single color or a specific piece count at a low per-piece price. Choose Custom Mix if you want to hand-pick a personalized assortment of colors and piece counts. Bulk favors volume and value; Custom Mix favors control and variety.
You are ready to expand your Plus-Plus collection, but the options can feel overwhelming. Bulk bags offer one color in large quantities, while Custom Mix lets you choose exactly which colors and how many pieces you get. The right choice depends on whether you value volume or variety more.
This comparison breaks down the real differences using supplied catalog facts, so you can decide which option fits your building habits, budget, and storage space. We will also highlight specific products like the 150 pc Bag - Neon Yellow and the 150 pc Bag - Glitter Transparent to show how bulk works in practice.

What is Plus-Plus Bulk?
Plus-Plus bulk refers to large-format bags or boxes that contain many pieces of a single color or a themed assortment. For example, the 150 pc Bag - Neon Yellow contains 150 pieces in one vibrant color, and the 150 pc Bag - Glitter Transparent contains 150 pieces in a glittery transparent finish. These are designed for builders who need a specific color to complete a project or who want to stock up on a favorite hue.
Bulk sets are often priced lower per piece than smaller tubes or boxes. The catalog price for the 150 pc Bag - Neon Yellow is USD 6.00, compared to a comparison price of USD 11.99, making it an economical choice for filling gaps in your collection. However, bulk typically limits you to one color per bag, so you may need multiple bags to get a range of colors.
- Best for large single-color projects, mosaics, or replacing frequently used colors.
- Per-piece cost is usually lower than buying multiple small tubes.
- Storage is simple: one bag, one color.
What is Plus-Plus Custom Mix?
Custom Mix is a build-your-own option that lets you select the exact colors and quantities you want. Instead of committing to 150 pieces of one color, you can create a personalized assortment that matches your project or your child's favorite palette. This is ideal when you need a balanced set of colors for open-ended building or when you want to try new shades without buying full bags.
The trade-off is that Custom Mix may not offer the same deep discount as bulk, because you are paying for curation and flexibility. You also need to plan your mix in advance, which can be a fun activity but requires more decision-making than grabbing a pre-filled bag. If you enjoy tailoring your supplies, Custom Mix gives you control that bulk cannot match.
- Best for builders who want a specific color palette or a balanced assortment.
- Allows you to try multiple colors without buying full 150-piece bags.
- Requires planning: decide colors and counts before ordering.
Key differences: volume vs. variety
The core difference is volume versus variety. Bulk gives you a large number of pieces in one color, which is perfect for color-specific builds like a neon yellow race car or a glittery transparent castle. Custom Mix gives you a smaller total count but across multiple colors, which suits open-ended play where children switch between colors frequently.
Another difference is predictability. With bulk, you know exactly what you are getting: 150 pieces of a single color. With Custom Mix, the final assortment depends on your selections, so you need to think ahead about how many pieces of each color you actually need. If you are building a large mosaic, bulk may be more efficient; if you are building a variety of small creations, Custom Mix may be more practical.
- Bulk: high volume, single color, low per-piece cost.
- Custom Mix: moderate volume, multiple colors, higher per-piece cost but tailored.
- Consider your typical build size and color needs before deciding.
When bulk makes more sense
Bulk is the better choice when you have a specific project that requires many pieces of one color. For example, if you are building a large Plus-Plus mosaic of a sun, the 150 pc Bag - Neon Yellow gives you a dedicated supply of yellow pieces without leftover colors you may not use. Similarly, the 150 pc Bag - Glitter Transparent is ideal for adding sparkle to a specific section of a build.
Bulk also works well for classrooms or playgroups where multiple children build simultaneously and certain colors run out quickly. Buying a bulk bag of a popular color ensures you have enough pieces on hand. The lower price per piece (USD 6.00 for 150 pieces) makes it budget-friendly for replenishing your most-used colors.
- You need many pieces of one color for a large build.
- You are restocking a color that is frequently depleted.
- You want the lowest cost per piece for a single color.
When Custom Mix makes more sense
Custom Mix shines when you want a balanced set of colors for open-ended creativity. If your child builds a different animal or vehicle every day, having a variety of colors on hand is more useful than a large quantity of one color. Custom Mix lets you create a palette that matches their interests, whether that is a rainbow of brights or a set of earthy tones.
Custom Mix is also a good way to try new colors without committing to 150 pieces. If you are unsure whether a glitter transparent piece will work in your build, you can add a small quantity to your mix and test it. This flexibility is valuable for builders who like to experiment or who are new to Plus-Plus and want to explore the color range.
- You want a variety of colors for open-ended building.
- You want to try new colors without buying a full bulk bag.
- You enjoy customizing your supplies to match a specific project.
Trade-offs at a glance
- Cost per piece: Bulk bags like the 150 pc Bag - Neon Yellow offer a lower cost per piece (USD 6.00 for 150 pieces) compared to smaller tubes or custom mixes. If budget is your main concern, bulk wins for single colors.
- Color variety: Custom Mix lets you choose multiple colors, while bulk locks you into one color per bag. If you need a range of colors, Custom Mix or a pre-mixed tube like Tube - Rainbow is better.
- Planning effort: Bulk requires no planning beyond picking a color; Custom Mix requires you to decide colors and quantities in advance. Choose bulk for simplicity, Custom Mix for control.
- Storage: Bulk bags store easily as one color per bag; Custom Mix may arrive as a single assortment that you may want to sort. If you prefer organized storage by color, bulk is simpler.
