Clearly has not been tested

This kit was offered to my six year old daughter. As she is a little small to make only the bracelets I helped. She puts the beads and holding the girls while I get the bracelet.
The kit allows for six strap. There are five colors of nyon son (pink - blue - purple - orange and two black) and matching pearls.
No problem for mounting the first strap (black son and engraved beads) but in the second there is a problem: the nylon thread does not pass through the holes rhinestone beads and beads because their holes are too narrow.
I fierce for 15 minutes for rhinestone beads - successfully thankfully - but impossible to pass the wire through the beads. I sû improvise and use large beads but shame. A priori the kit has not been tested before the sale!
Otherwise nothing to say, my daughter is really happy.
