Silicone Bento Box Dividers — 3-Shape Reusable Muffin Cups
Product description
A practical set for packed lunches and small-batch baking, these silicone dividers are designed to fit into most bento boxes and standard muffin trays. The set includes three shapes — round, square, and rectangular — in sizes that suit common containers and pans.
Round: 2.8" × 2" × 1.3" — fits standard muffin wells. Square: 2.75" × 1.78" × 1.3". Rectangular: 3" × 2.2" × 1.3". The shallow profile avoids sharp corners and the bright hues brighten meals while keeping components separate.
Crafted from food-grade silicone, these cups are non-toxic, odor-free, and BPA free. They are uncoated and resistant to staining, and can be used across a wide temperature span from -104°F up to 446°F, so they work in freezers, refrigerators, microwaves, and ovens.
Cleaning is straightforward: rinse, hand-wash, or place on the top rack of a dishwasher. Because they’re reusable, they offer a long service life compared with single-use paper liners, and can be used repeatedly for snacks, baking, or freezing.
Beyond lunchboxes, these dividers are useful for baking muffins and cupcakes, portioning charcuterie or snacks, freezing smoothie portions or small treats, and other kitchen organizing tasks. They pair well with other silicone baking cups and bento accessories for a cohesive meal prep system.
Pros
- Reusable, food-grade silicone
- Fits standard muffin pans and bento boxes
- Easy to clean and temperature resistant
Cons
- Pack may include more cups than some need
- Occasional missing or mismatched colors reported

VerdictThese silicone bento dividers are a flexible, reusable solution for keeping lunchbox items separated and for small baking or freezing tasks. They come in three common shapes and standard sizes that match muffin pans, are made of food-grade, BPA-free silicone that tolerates a wide temperature range, and wash easily. They’re colorful and kid-friendly, but the pack size can be larger than some users

Perfect for kids' lunch packing
Great for separating foods and even holding dips. I toss them on the dishwasher's top rack and they come out clean. Flexible, easy to use, and the bright colors are a hit.

Multipurpose and color-coded
Not super thick but sturdy enough for charcuterie or kids' snacks—strawberries in one, nuts in another. I like using different colors to mark spicy items.

Works well, roomy set
They function fine. I rated four stars because the set contains more cups than I need; a smaller, cheaper option would be handy.

Exactly what I wanted, packaging issue
They meet my needs, but the listing images suggested 14 of each shape while I received 12 of each. Still usable, but the photo/count should match; I was also missing the dark green pieces.
