This craft is to achieve exactly the right length, especially if you do not just bracelets and charms you make. Price is more than correct and elastic provided are fairly resistant and beautiful color. Point of view of the strength, it suits me perfectly since I am careful adult but be careful with young children, they might want to take it apart and there, to go up without any break, good luck. What more? The only notable absence is the hook. This kind of small hook is really tough but really not ... However, it is very easy to find a suitable hook commercially at affordable prices and that provided sensitive, so be complex montages .
