A dump truck and a front loader. Both are included in one box - the dump truck has a tipping bed, and the loader has a movable scoop bucket. Two different vehicles, two different play patterns, one purchase.

Fair question. At 20 × 12 × 11.5 cm, they're noticeably bigger than palm-sized toy cars but nowhere near the 69 or 83 cm DOLU trucks sold separately. Jumbo here means larger than a typical small-scale toy vehicle - sized for a 2-year-old's hands rather than for display or collector use. Substantial enough for sandpit play, not so large they're awkward to carry.

Both move. The dump truck bed tilts to tip out its load, and the loader bucket raises and lowers manually. Neither is motorised - kids operate both by hand, which is exactly right for the 2-year-plus age group this is made for.

The minimum is 2 years, mainly because of the moving parts and the play patterns they support. At 18 months, most toddlers will push the trucks around and mouth them rather than engaging with the tipping or scooping mechanism. A few months makes a real difference here. Worth waiting, or supervising closely if you go ahead earlier.

Yes - that's one of the better use cases for this set. The dump bed loads up with sand easily, and the loader bucket can scoop small amounts. The plastic is durable and weather-resistant. Sand will get into the hinge points of both vehicles over time, but that's true of any toy used regularly in a sandpit and doesn't affect function much at this scale.

The 6140 is a single vehicle per pack, supplied at random - either a truck or a loader. The 6144 gives you both in one box, so you know exactly what you're getting. For a child who wants to run a full construction site with two vehicles working together, the 6144 is the more practical choice. The 6140 works better if you just need one specific vehicle to complement something they already have.

Genuinely well-suited for that. Each child gets their own vehicle with a different function, which naturally reduces the "I want what they have" problem. The dump truck and loader complement each other during play - one scoops, the other carries - so kids tend to cooperate rather than compete, at least some of the time.
