Used LEGO is easy to find in the Netherlands, both as loose bricks by the kilo and as complete sets. Bulk lots are cheapest per brick but come mixed with dust, other brands and missing parts. For a specific set, check completeness against the online parts list before you pay, and learn to recognise the copy brands.
A bulk lot (lego partij) is a box or bag of loose bricks sold by weight. It is ideal for free building and for kids who do not care about instructions. Sets are sold with or without box and instructions, and their value depends heavily on completeness, especially of the minifigures.
If you want a particular set, search with the set number. LEGO prints a four to six digit number on every box and instruction booklet, and sellers who know what they have usually put it in the title, like 'Lego 42115' or 'Lego City 60337'.
Unsorted mixed LEGO typically goes for around EUR 10-18 per kilo, depending on how clean it is and what is in it. Lots with lots of Technic, minifigures or recent themed pieces go higher. Duplo is cheaper per kilo because the bricks are big and heavy. Be wary of lots weighed in the storage box: ask for the weight without the container.
Ask for a photo of the bricks spread out on a table, not just a closed tub. Big baseplates and storage boxes add weight but little play value.
Copy brands such as Lepin (now mostly gone), Mould King, Cada, Lele and many unbranded 'bouwstenen' sets are sold alongside LEGO, and bulk lots often contain some mixed in. Some are clones of official sets, sold at a fraction of the price. Genuine LEGO has the word LEGO moulded on top of every stud (except some very small and transparent pieces) and on the inside of many parts.
Copy bricks often feel slightly different, clutch too tight or too loose, and have a duller colour. In a bulk lot a few stray copies are normal. A 'complete Star Wars set' at half the usual price with no box and no LEGO logos is a copy.
Bulk lots arrive dusty and sometimes sticky. Wash the bricks in a mesh laundry bag or a bucket of lukewarm water (not hot, which can warp them) with a bit of dish soap, then dry them on towels. Keep stickered pieces, electrical parts and printed bricks out of the wash, and never put LEGO in a dishwasher at high heat.
Some retired sets, especially large Star Wars, Creator Expert and Modular Buildings, sell for more than their original price, and you will see them listed sealed (nieuw in doos, sealed). Treat sealed boxes with care: check the tape seals on the sides and that the box is not crushed. If a seller asks well above typical BrickLink prices, ask why. For bulk with specific contents, such as mostly Technic with motors within driving distance, a plain-language search on vindje.com can sort the useful lots from the Duplo and copy brands.

Mixed, unsorted LEGO usually sells for about EUR 10-18 per kilo in the Netherlands. Clean lots with Technic or minifigures go higher.
Look for the LEGO logo on the studs and inside the bricks. Copies have no logo or a different brand name and often a duller colour.
Look up the set number on Rebrickable or BrickLink to get the parts list, then compare it with what the seller has.
Use a laundry bag on a cold, gentle cycle at most, or wash by hand in lukewarm water. Keep stickers and electronics out of the water.
