1 / 7Optimal Products 21544 35 L Clear Plastic Storage Box with Lid
Optimal Products 21544 is a clear plastic storage box listed at 35 litres, with a lid and stackable design. Its stated dimensions make it a potential fit for compact household storage, but the listing conflicts on whether the selected set contains four or five boxes.
At a glance
- Clear base and clear lid are claimed, allowing contents to be seen without opening the box.
- The listing says the boxes can be stacked with or without the lid attached.
- The claimed 45 x 35 x 23 cm size and 35-litre capacity give a practical reference for checking available space.

Listing details to confirm
The listing is contradictory about quantity: the title says 5 boxes, while a feature says a set of 4. The selected pack quantity is unconfirmed. It also gives conflicting item counts and descriptions of the lid closure, and says the lids may stack with or without attachment. Confirm the selected variant and lid design before buying.

Customer feedback highlights appreciation for the boxes' size, quality, stackability and usefulness for under-bed storage and smaller items. Reports about sturdiness and fit are mixed, while some customers say lids do not click shut or stay in place. That makes the listed dimensions useful for planning space, but lid retention and the conflicting pack quantity matter if the boxes will be moved or stacked.

- Customers describe the boxes as stackable.
Negative themes

Frequently asked questions
How many boxes are included?
The listing conflicts: its title says five boxes, while a feature says the set contains four. Confirm the quantity for the selected option before ordering.
What are the stated dimensions and capacity?
The listing gives approximate external dimensions of 45L x 35W x 23H centimetres and a capacity of 35 litres.
Does the lid lock shut?
The listing describes a lift-off lid and also gives a gull-wing closure type, so the closure design is unclear. Customer feedback also reports that some lids do not stay shut reliably.
Can these boxes be stacked?
The listing says they are stackable with or without the lid attached. Customer feedback describes positive experiences with stacking, alongside mixed reports about fit.
