A fold­ing ruler offers the ide­al space sav­ing solu­tion to fit a 30cm ruler into a stan­dard size pen­cil case. Helix was found­ed 130 years ago in the Mid­lands, Eng­land with a view to offer cus­tomers high qual­i­ty, stur­dy and durable sta­tionery to use every day in school, at home or in work. Today Helix’s prod­uct range may have grown from where it all start­ed 130 years ago but Helix still has the love and pas­sion for sta­tionery that it always had, as well as the desire to offer peo­ple the best of British design and func­tion in their every­day sta­tionery use.

    No impe­r­i­al mea­sure­ments on it, just two edges of Met­ric.….The media could not be loaded.

     Does what it is sup­posed to do in as much as it folds and at a rea­son­able price. What it does­nt do (nor the oth­er two that I bought for my kids back to school) is have any Impe­r­i­al mea­sure­ments on it. Now cor­rect me if I’m wrong but we live in the UK, pur­chase in the UK and mea­sure in the UK, that hap­pens to be both impe­r­i­al and met­ric. More fool me for not look­ing at the pic­ture more care­ful­ly but bad from Helix that they sell a met­ric only ruler in this country.…..

    Amaz­ingThis is very good as it fits in my pen­cil case and unlike lots of fold­able rulers this one does­n’t leave a dent in the mid­dle when draw­ing a long straight line.

    Broke in the first 2 weeksThis item seemed like a great idea because it could be kept in a small pen­cil case but still pro­vide a good length. Unfor­tu­nate­ly, the hinge was weak and it snapped with­in the first 2 weeks of hav­ing it.

    Not very good qual­i­ty.I bought these for my daugh­ter to take to school and I must admit when it arrived I did think this won’t last long as it seemed cheap qual­i­ty. Sad­ly I was right and it snapped on day two. Prob­a­bly not a great prod­uct for a child. Maybe ok for an adult.

    It rules !So my son had it 48 hours and broke it 😆Great ruler but typ­i­cal kids he sat on it and it snapped 🤦‍♂️But nev­er­the­less it did the job and we will buy another.

    Essen­tial I am toldNot very durable. I seem to buy loads of these. But it fits nice­ly in a blaz­er pock­et and is prob­a­bly used/abused by my 12 year old so the lack of dua­bil­i­ty may not always be the rular itself.

    Issues…Likes — I like that it is fold­able and as I’ve had one before I thought I’d buy one again!Dislike — The one I got had a crack in it, so I had to refund it and wait till tomor­row to get it again! Also, fold­able rulers have a ten­den­cy to snap after a while.Great ser­vice — Returned it with­out need­ing to do any­thing extreme­ly hard would rec­om­mend to buy this!

    Dis­ap­point­ed with the qual­i­ty.It was used and kept in school for few days, not tak­ing back home due to Covid. But the link­age was bro­ken only after few usages. My daugh­ter said her class­mate also bought one and was bro­ken too.It would be much appre­ci­at­ed if sup­pli­er can send a replace­ment! Thanks.

    Nice prod­uctThe prod­uct is good but the deliv­ery was all wrong as it was thrown through my win­dow where chil­dren were play­ing with­out me hear­ing the door be and my chil­dren were scared all through the day. He or she could­n’t even press and repeat­ed it at all. It was in a big pack­age with oth­er things so I find it very upsetting.

There was a slight gap between the inter­sec­tion of the two sep­a­rate 15cm rulers which made draw­ing a line longer than 15cm cause it to “swerve” slight­ly and hence, not draw a straight line. A big prob­lem as draw­ing a line big­ger than 15 cm whilst main­tain­ing that par­tic­u­lar size is the rea­son I pur­chased this product.
