jouet pour enfants qui montre le principe des poles nord et sud d'un aimant
however, my pen had no ink in it! so kind of defeats the purpose of a floating pen. I'll see if the magnets fit one of my own pens to resurrect this gift.
El pedido ha llegado tal y como se describia, bien envuelto en material protector.
great tech from BG
very easy but nice little project to teach kids about magnets
Floating pen package arrived okay, packaged properly and undamaged. It was value for money and looks great.
tutto bene
تمام
I found it was not so easy to make it work so I would not buy it again
Забавная вещица.
