Quick Answer
Fun Fillers are loose, open-ended sensory play materials that you add to bins, water tables, or any container you already own. Sensory Jar fillers are the soft-touch silicone shapes and light-up elements that come inside a specific jar system. If you want flexibility and a lower entry point, start with Fun Fillers. If you want a self-contained, portable sensory experience with a built-in glow element, a Sensory Jar set is the better fit.
Both Fun Fillers and Sensory Jar fillers add texture, color, and interest to sensory play. The confusion comes from the word 'filler' — it sounds like they do the same job. In practice, they serve different play patterns, different ages, and different levels of adult setup.
This comparison breaks down what each one actually is, where each works best, and the honest trade-offs so you can pick the right sensory play materials without buying twice.
What Fun Fillers Actually Are
Fun Fillers are loose sensory play materials designed to be poured, scooped, sorted, and combined. They are not a container or a toy with a fixed shape — they are the contents. You decide the bin, the water table, or the bowl they go into. That open-ended format is the point: the same filler can be a digging medium one day and a pouring activity the next.
Because they are loose, Fun Fillers suit kids who are past the mouthing stage and can play with some supervision. They also work well alongside other Glo Pals items, since you can add them to a water table that already has Light-Up Cubes or characters in it.
- Best used in a tray or bin with a defined edge so pieces stay contained
- Pair with scoops or cups to extend the activity and build fine motor skills
What Sensory Jar Fillers Actually Are
Sensory Jar fillers are the soft-touch silicone shapes that come inside a Sensory Play Jar set. The Mini Sensory Play Jar Set – All 3 Colors includes three jars — Gumdrop, Firefly, and Blue Lagoon — each packed with 5 soft-touch silicone shapes sized for little hands. The jar itself is the container, so the play experience is self-contained and portable.
This format suits younger children and travel because everything stays in one place. There is no loose filler to spill across the floor, and the jar can be capped and carried. The trade-off is that the contents are fixed to that jar system — you are not swapping in different materials the way you would with open fillers.
- The jar acts as both storage and play surface, which simplifies cleanup
- Three color options let you rotate jars rather than buying new filler material
The Core Trade-Off: Open-Ended vs Self-Contained
Fun Fillers win on flexibility. You control the container, the amount, and the combination. That makes them easy to scale up for a bigger sensory bin or scale down for a quiet table activity. The cost is that you need to supply the container and manage the mess.
Sensory Jar fillers win on convenience and portability. The Mini Sensory Play Jar Set – All 3 Colors gives you three complete play experiences in one bundle, each with its own color theme. You do not need to source a bin or decide how much filler to pour. The cost is less variety in texture — you get the silicone shapes and the jar, not a rotating cast of loose materials.
Neither is better in the abstract. The right choice depends on whether your priority is adaptability or simplicity.
- Choose Fun Fillers if you already have bins or water tables and want to vary the contents
- Choose a Sensory Jar set if you want a grab-and-go option with no setup decisions
How They Work With Light-Up Play
Glo Pals is known for light-up elements, and both filler types can connect to that. The Mini Sensory Play Jar Set – All 3 Colors is part of the same ecosystem, so the jars can sit alongside light-up characters during play. If you want to add a character to the mix, the Pippa® Light-Up Character includes 2 Liquid-Activated Light-Up Cubes and works in baths, water tables, and sensory bins.

The Alex® Light-Up Character also includes 2 Light-Up Cubes and is designed to be collected alongside other Glo Pals characters. Adding a character to either filler type extends the play pattern — the filler provides texture, and the character provides the glow and a narrative element.
Alex® Light-Up Character
- Light-Up Cubes are liquid-activated, so they pair naturally with water-based filler play
- Characters give kids a focal point when the filler alone loses novelty
Trade-Offs at a Glance
- Flexibility: Fun Fillers let you change the container, the amount, and the combination. Sensory Jar fillers are fixed to their jar system. If you like to vary sensory play materials week to week, Fun Fillers give you more room to experiment.
- Setup and Cleanup: Sensory Jar fillers stay contained in the jar, which simplifies both setup and cleanup. Fun Fillers require you to provide a bin or tray and manage loose pieces. For busy days or travel, the jar format reduces the number of decisions and the mess radius.
- Age and Supervision: Loose Fun Fillers suit kids past the mouthing stage who can play with some supervision. The jar format is easier for younger children because the contents are enclosed. Match the format to your child's current stage rather than buying for the age you expect next year.
- Extending With Light-Up Play: Both formats can incorporate light-up elements. Pippa® and Alex® each include 2 Light-Up Cubes, which activate in water and work in bins, baths, and water tables. If glow play is the main draw, add a character with included cubes rather than buying cubes separately.

Which One Fits Your Family?
Choose Fun Fillers if you:
- Already own sensory bins, trays, or a water table and want to vary the contents
- Want open-ended play that can scale up or down depending on the day
- Are comfortable managing loose pieces and supervising the play
Choose a Sensory Jar set instead if you:
- Want a self-contained, portable option with no container to source
- Prefer a fixed set of contents that stay together for travel or quick cleanup
- Are buying for a younger child who does better with enclosed play materials
Fun Fillers and Sensory Jar fillers solve different problems: one gives you flexibility, the other gives you convenience. Pick based on how you actually run sensory play at home, not on which sounds more versatile. If you want both, start with a jar set and add loose fillers later when you know what your child reaches for.
