Why stationery buyers need detail
To most people a notebook is a notebook. To the people who buy from a stationery shop, it is paper weight, ruling, binding and whether fountain pen ink bleeds through. Those buyers read every detail and ask about what is missing. A shop inside Telegram lets them ask in the same chat where they order.
Organise the catalogue
Keep the categories simple: notebooks, planners, pens, paper and cards, desk accessories, gift sets. Inside notebooks, the ruling matters most, so put it in the product name: dotted, lined, blank, grid.
Write the specs buyers check
For a notebook: size, number of pages, paper weight, ruling and binding. For a pen: the type, the tip size and the ink colour. For a planner: dated or undated and the layout. Put these first in the description in a short list. Buyers who care will look for them; buyers who do not will skip them.
Photos up close
Show the cover, then an open spread, then a close-up of writing on the paper. That last photo answers the question about ink and texture better than any spec. Shoot in daylight on a plain surface, and keep the same angle across products so the catalogue looks consistent.
Gift sets sell themselves
A notebook, a pen and a pack of cards make a gift that is easy to choose. The bundles block lets you sell such a set as one product with one price, and gift cards are a storefront block too for people who cannot decide. Before holidays, a post in your channel about gift sets with a button to the shop is usually your busiest week.
Orders and payment
By default the order reaches you in Telegram without payment taken, and you confirm it with the buyer. On a paid App plan with your own bot you can accept card payments inside Telegram, with the money going to your own Stripe account.
