Easy to build once, but the real fun happens after experimenting with different combinations. Rainbow arches and rainbow circles are my favourite patterns to make!
41900 Rainbow has tiles befitting that description. Both of the 1x1 printed rainbow tiles were used in 21045 Trafalgar Square, but the quarter circle printed rainbow piece is new to this set. Of all the bracelets, I think this is the least exciting to AFOLs, mainly because there aren't many pieces here that we haven't seen before.
Beyond as a fashion accessory for a child, what utility do these bracelets have? They are likely to be show up on the wrists of adult fans at conventions, and knowing how inventive the community is will no doubt find their way into fan builds too – the flexibility that they offer may come in handy.
As someone who likes colours, the designs have been well thought out and I can see the new printed tiles appearing in MOCs giving a great reason to buy a few packs to play with or simple use as parts packs for your own building enjoyment. Such fun!
