rootduckThanks for your message! Always nice to meet a fellow fan of magnets. It’s great to hear that you’ve got a good set of magnets. When you purchase magnet sets from vendors outside of pro brands, you never know what you’re going to get, thank goodness you're satisfied with the ones you bought. In the case of Nanodots, you can expect the same experience each time. We guarantee it.
Nanodots are designed and manufactured to be the highest quality magnet constructors for the casual fidgeter or the avid collector or pro builder. Beyond being incredibly clicky, tactile and fun on their own, we include a key in each tube of Nanodots to Dotpedia.com - an infinite building guide. You’ll find 100s of HD guided videos so you can build awesome things. Come check it out! :)
