I've been crocheting for 15 years. I've tried every brand....I prefer a Boye shaped hook-- which these are. (Susan Bates just never really worked out well for me.) Anyway, these Tulip hooks are kinda pricey if you buy a set, so I've just been buying them as I've needed them. I pretty much only just G, H, I, J hooks anyway. (They're sold in metric sizes, so be sure to check. Basically, if you're like me-- you'll want the 4mm/4.5mm/5mm/5.5mm and possibly the 6mm. Hope this helps.
