We used the eyelets to attach to an invitation card, a belt. The handling of the supplied punch and impact piece is pretty easy, you should use a rubber mallet and a non-slip surface on top. With a normal hammer it works well, the plastic parts keep in normal handling in any case the 15 eyelets. Would I buy it again, possibly smaller in diameter. The missing in the description, which are 11 mm, the inner diameter, the eyelet itself is greater then total.
