Question: Can these be used with ANY Lego sets or are they specifically for the "Friends" sets?
Document: Helping my daughter to organize all of her Lego Friends sets. Comes with 4 sorting trays. You can buy double stack them if needed. I plan on ordering to more trays from Lego.
This was the only lego organizer I could find that was girly and would go with my daughters lego friends sets. Great product, but it took forever to arrive and was pricey compared to the other ones.
The plastic is good quality, it arrived fully assembled. Love the colors, coordinates very well with the Lego Friends sets. The drawers hold 4 transparent sorting trays with various size cubbies.
Love it! Definitely a lifesaver for organizing my daughter's lego friends.
I would recommend this to any parents who want to help their child organize their Legos. Works well for Lego Friends and I'm sure it would work for other kits.
These boxes are great for the little type-A kids. My daughter sits for hours sorting her lego sets and putting certain things in each little cubby. And the drawers are convenient enough that the kids actually keep the legos off the floor.
Love that the color scheme matches Friends and the price was reasonable. This is hard to find including in the Lego store in NYC. Will likely buy another set of drawers as my daughter continues to add to her Friends collection.
This is awesome! Now I have storage for all of the pink, purple and green legos from my daughters sets. Being able to seperate them from brothers is a bonus, however this system stands on its own feet with the features. Love the organization, combined with the ability for building on the top tier! !
This box is divided into many small lattice, now my son's Lego toys never worry about failing to find accessories
This item is really great when working on a big lego project. you are able to sort your pieces accordingly which makes the building process much easier then just dumping the piece in a box or on the floor. Very well made.
Answer: This can be used for ANY type of Lego sets.  It's amazing at how much you can put into these drawers.  Really happy with this purchase and may even get another one once this one is full.
