Rank #6 in Best Safe 2026: The Box Weighs 1.87kg
Bonsaii 6.6-Litre Small Steel Safe Box with Key and Expansion Bolts
Price and rating as shown on Amazon when we collected them. Both change.
The Bonsaii is the cheapest 6.6-litre safe in this ranking at £18.69 and weighs 2.04kg, with a key lock, a pry-resistant door and — unusually — the expansion bolts to fix it down included.
It takes sixth because it is the best deal of the small safes: the cheapest, with the hardware that turns a carryable box into a fixed one, and 630 ratings at 4.4 stars behind it.
How those 630 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

Questions people ask
Why do the bolts matter?
Because a 2kg safe that is not bolted down can be picked up and carried away; the bolts are what make the steel relevant.
Does it need batteries?
No, it is a key lock.
How big is it inside?
6.6 litres, measuring 17 x 23 x 17cm outside.
Is it fireproof?
No, and the listing does not claim it is.
Why is it sixth?
It is the cheapest small safe here with the fixing hardware included, and a key lock rather than a keypad.
How many ratings does it have?
630 at the time of collection, averaging 4.4 stars, with 72 per cent five-star and 4 per cent one-star.
