These pens were just what I needed for Kay Arthur's Inductive Study Bible. It has the colors you need to mark Jesus, God, the Holy Spirit and Satan. Also the land you are studying at the time including Israel. the laws, the Gospel, love, pray etc. You would have to be using them for what they are made for which is a special type of Bible study. It more than makes up for what people consider flimsy. There are a lot of other markers that are sturdier but not with the exact colors and pens for note taking in the margins. If you want something sturdier try the Micron pens which are also made for the Inductive study method. I am so very happy with my purchase!
I love this set, there is a lot of options when it comes to note taking. I also like the stylus on the end of some of the set for those of us who use electronic bibles sometimes. I use the magnifier on my new bible and it works great.
I was surprised by how light these pens are and the location of the "click on" mechanism. Wish they were of a better quality, but they will do the job I will be using them for. Maybe additional, brighter colors could be added to this set to add variety to Bible marking. Overall, a great buy for the price and a great tool for Bible study!
