I've been using it for a couple of months now, and it's awesome! I always have my pencils and everything with me wherever I go. Especially good if you sketch a lot on the go.

Great product.

This pen holder is amazing. I have an A5 size 6 ring binder for my planner/bujo and I wrap this around the whole journal and I can carry multiple pens with me. I’ve had it for several months and so far it’s been terrific. Its top pocket is big enough to put a small tube of lotion also, which is great because I often don't carry a purse. Also, recently I traveled and realized the side pocket is perfect to slip my passport and travel documents into. It’s also good for receipts and little slips of paper. Overall, it’s sturdy and well made. The Velcro allows it to fit journals and books of various sizes and thicknesses, so I could use it on books that are smaller or bigger than my A5 binder. I really love this pen holder and I’m glad I bought it. It’s super useful!

Excellent carry, great economy and flexibility for business and casual use.
