Before you use it, tea bags are inserted into it. Make sure that they are touching the rear stopper. A tea bag can then be inserted from above into the small window for show purposes. Make sure the brackets do not bend away.

If this is too much the case, you can stick or flame the support in place, but then there will be less space for tea in the holder.

Of course you can print the support multiplice times and attach it higher so that more tea can be storaged.
